Round 1

Resume Shortlist

Interview Experience
There were 3 Job profiles open of opera solutions (Solution Analyst, Analytics Specialist, and Software Engineer). Students are asked to sign just for one profile. There was a test for analytics and software profile and direct interview for solution profile (Consultant profile).
Interview Tips
Spend enough time before choosing the profiles. Spoke to senior who had a similar job and figure out your best suitable profile and prepare accordingly.
Round 2

Test

Duration
60 min Minutes
No. of Questions
20+5 questions
Test Sections
  • Section 1: Objective
  • Section 2: Subjective
Interview Experience
Opera solution conducts workshop for shortlisted candidates. In the workshop, they mostly tell about technical part behind big data management such as Mainframe and Hadoop. After the workshop, the test was conducted. The test had two sections, the first section contains objective questions around 20-25 (I did not remember the exact number). Objective questions were of aptitude type (moderate level of difficulty). The second section contains 5-6 subjective questions, mainly focus on probability again the moderate level of difficulty. 30 students were shortlisted for next round (interview round).
Interview Tips
Start preparing as early you can. Practice problem daily does not wait for last few day. The main point of practice is to develop a habit of increasing accuracy and speed which is the crucial points of aptitude test.
For probability practice, there are online website and blogs you can take help from them. I have listed down some which are used. You should have some prior practice before setting for test otherwise, it would be difficult to do well in the test as some questions are tricky and difficult to solve in the first time.
For aptitude practice, you can refer TIME material, I think that is sufficient.

The interviewer gave me feedback and point out some area on which I can quickly look it for further interview.
Interview Tips
I have assigned a buddy, IIT graduate having the same specialization. (Opera solutions follow buddy program similar of other consultant company). I personally found out buddy program very useful, you should contact your buddy or at least talk to him ones. The information you get from a buddy is very helpful of preparing for an interview. You get some aspect on which domain you need to work.

I was interviewed on-campus at IIT Bombay for Consultant role at Opera Solutions
Interview Process
Resume Shortlist Case Study Interview
Round 1

Resume Shortlist

Interview Experience
I started preparing my resume somewhere around August end. I spoke to a few seniors about it and read quite a few resumes, especially of those seniors who either had a profile similar to mine or had secured jobs in fields of my interest, eg. Consulting, finance, etc. I also attended the Resume Writing Workshop conducted by McKinsey and Co. on campus and cleared a few doubts there.
Interview Tips
I would advise you guys to start preparing your resumes well in advance, it is not something to be kept for the last minute. Being the first form of acquaintance between you and a firm, it is a highly important document and the way you highlight your strong points and attributes can go a long way in shortlisting you from amongst the hundreds of resumes that they have to scan. Also, it is important that you be able to speak on any point in your resume in detail, hence you must be sure of what you are writing in it.
Round 2

Case Study Interview

Interview Experience
The procedure of selection for Opera Solutions was a set of 4 interviews, each having a case study and some HR questions. The initial shortlist had around 22 candidates, after the first 2 interviews around 10 candidates were selected for the final rounds. Finally 3 candidates were made offers.  There were no GDs, only case interviews. The first interview had a case involving a music company which scouts for amateur talent and launches them. They want to enter India and want you to analyse the market and suggest if its feasible or not. The interviewer gave a lot of data related to market share of pop music, bollywood, devotional music, etc and it suggested that the market share of the genre related to the company is very little. However I think what worked best was that I also pointed out certain solutions which could make it feasible, such as merging with another company in a genre where the given company has core competencies in. I think this was the high point of the interview which I atleast would like to believe compensated for a later interview that I did not do well in. Another interview had a case where a pharmaceutical company in the US wants to enter India. A set of constraints and data was given and I was asked to calculate if it should actually setup a manufacturing facility in India or manufacture in the US and transport to India. I did not do well in this one, I wasn’t being able to come up with a figure. Both the interviews had an HR component where I was asked about my strengths and weaknesses, about Mood Indigo and my academic record. I was asked to describe myself. I was also asked to talk about my co-intern’s project in ITC (she was also interviewing with Opera). In a subsequent interview after the shortlist, I was asked to estimate the market for Maruti cars, domestic air travel. They weren't expecting too much detail, the interviewer was more interested in the approach. point.
Interview Tips
I attended most of the initial PPTs. One does get a good understanding of what a firm does and where exactly do you fit into it, you also understand what they are looking for and what is the extent of their operations. I must admit though that I found my interaction with seniors, especially those working in those firms was more informative and fruitful. They can give clarity in certain grey areas that companies might stay non-committal on.ending across links/documents would help us compile a single point resource) . I prepared for case studies from the material I took from seniors, most of which is available on the LAN. For case studies I prepared with a friend and sometimes in groups of 3. I think this method is better than individual preparation because the other person can point out where you are going wrong, you get a different perspective and at the same time you can prepare in a fashion where one interviews the other and vice versa, so you get slightly comfortable with how an actual interview might feel like. It is however important to ensure that the person you are preparing with is competent and complementary to your skill sets, so that you can improve upon aspects where you might be lacking in.
General Tips
Case studies and HR questions. One should be very comfortable with points mentioned in the resume and should be able to talk at length about any . I guess it'd just be shifting a little from being myself if you know what I mean. A lot of seniors would give you a lot of fundae, but at the end one must remember that unless one is comfortable with a certain way of speaking or certain method of solving cases, it wont look genuine. For example, one need not thrash out every single detail of a case before beginning to solve it, sometimes the interviewer might get impatient or might think you are trying to buy time to think by asking unnecessary details. So if you are the kind of a person who can intuitively draw good conclusions at the outset so as to decide which direction to proceed in and hence which questions to ask, you can surely go ahead and do that, you need not also ask questions that you know are not required. Case interviews are very feel-good interviews, even if you make a mistake you will be guided back on track by the interviewer, hence I personally would recommend that you stick more to your general approach to solving cases (if you know it is a good one and works of course) and not try to change too much just because a certain senior did it in a different way.

Opera Solutions BUSINESS ANALYST interview

Application
I was interviewed on-campus for BUSINESS ANALYST role at Opera Solutions
Interview Process
Resume Shortlist HR Interview HR Interview HR Interview
Round 1

Resume Shortlist

Interview Experience
Resume is the candidates face before the interview. All the things that he/she wants to communicate should be communicated well and in an organized manner. Giving excessive and irrelevant information doesn’t heed well with the company and the recruiting staff. For, non-core jobs a long resume is not necessarily a good resume. They generally prefer a short and concise resume giving only the details relevant to the job profile being offered. For example, for a post of Business Analyst giving a long list of technical and course projects will not help the candidates cause. I personally focussed a lot on Position of Responsibilities and extracurricular activities, especially those showcasing my leadership and oratory skills.
Round 2

HR Interview

Interview Experience
The first interview began with some questions about me. The interviewer asked me to tell something about me and my hobbies. Then he moved on to my resume and asked questions related to my intern and the PORs I had held and asking me to give a brief description about the duties involved. These questions were basically to ease me into the interview. Then he asked the routine interview questions like why consulting, why not a core job, what makes you think you are suited for this job. He asked me to relate some incident that showcased my leadership and teamwork skills. After the HR part, he gave me a case study. I was asked to estimate the market size of the bulbs market in India. It was an easy enough case study and I asked a lot of questions like whether I have to estimate for commercial and domestic both, for bulbs and CFL both etc. The catch in the question was to consider the replacement ratio for the bulbs and CFL.
Round 3

HR Interview

Interview Experience
The second interview also had a similar beginning with the routine questions. Then he moved on to case study which was a number crunching problem. He gave me almost no details and just narrated the situation. I had to as all the questions probing for the numbers and the data. The case went on as he kept elaborating the case with new additions.

Also, the interviewer was senior partner in the firm and I felt that I had made a genuine rapport with him. I felt free and asked him a lot of questions about his job, the job profile and how important an MBA degree is for the future. He explained me the details and I had a very healthy communication with him.
Round 4

HR Interview

Interview Experience
This one was pretty short and quick. The interviewer decided to ask me questions about my hobbies. We discussed about Hollywood movies, actors, football and my other interests. We both shared an interest in Hollywood movies and we had a nice time discussing the merits of my favourite actor, MORGAN FREEMAN. Then he gave me a puzzle. There are 25 horses and only 5 can race in one race. I had to determine the fastest three horses in the minimum number of races (the answer is 7. Try it out. It’s not very tough). I was not able to solve the puzzle on my own but he guided me with various clues and finally I was able to complete the puzzle with his help.
Interview Tips
Be prepared with the routine answers but don’t mug them up. Remember them in points and elaborate them as you go through the monologue. Answers to questions like why consulting and why should we hire you should be prepared very well. Prepare these answers yourself and don’t mug up some standard answers. The interviewer will know when you do that. Prepare some questions of your own about the job and the company and ask them to the interviewer when he gives you the chance. Don’t get nervous if you can’t get some question but instead try a new approach or ask for help.
General Tips
Focus a lot on extracurricular and PORs in the resume but at the same time keep it balanced. Prepare for case study interviews and puzzles. Be through with your resume and why you are there for the interview. Getting selected for the interview means you have an equally good opportunity as anyone else, so be confident.
Motivation for applying
The major information about the company was obtained from the pre-placement talk held by the company at the college campus. Also I talked to some of my seniors working there and in other consultancy firms as business analyst to get a feel about the profile and job description. Also enquiring about the attributes that the company majorly looks for from the seniors helped a lot.

Interview Process
Resume Shortlist HR Interview Case Study Interview Behavioural Interview
Round 1

Resume Shortlist

Interview Experience
I went through a few templates & took help from some seniors. I prepared a few drafts and then later made improvements. IT might be a good idea to prepare well in advance and get your resumes reviewed from seniors in the companies you are applying. As probably you'll get to hear a lot, focus more on what you have achieved rather than just stating what all you have done. Keep it simple and short. And don't add anything you are not comfortable talking about in an interview. I know many capable people who didn't get short listed for Mck/BCG just because they didn't think resume was a big deal. I attended most of the PPTs. They are informative, but don't always help you decide what you want, the best part are the pizzas of course. Talk to seniors in the companies that you are interested in but remember these seniors are now employees of the company and will usually not say a single bad word about the job. Apart from seniors, try talking to people who will give your interests priority over the company (cousins, close friends).
Round 2

HR Interview

Interview Experience
There was an initial shortlist of about 25 and a waiting list of 20 based on resumes. After the first round of interviews (one interview each), about 10 candidates were short listed. After the second round of interviews (2 interviews each), 3 final offers were made. All interviews were both case study and HR. A few questions based on the resume, the normal HR questions and a couple of them. Interview revolved around the normal HR questions, then he asked me something about which Indian company do I admire the most and why. To be honest I wasn't really prepared for this one. Next was a case of sort. He asked me that if I was the director of IIT Bombay and it was a private institute, what steps I would take to generate funds and make it a profitable institution. I think my answer revolved around generating funds from alumni, getting research grants from big companies, raising fees but providing adequate loans and repayment options, allowing shops inside campus, raising funds through placements.
Round 3

Case Study Interview

Interview Experience
The interviewer was asking everybody the same case, as he said he wanted to measure everybody on the same platform. I don't recall the case very precisely but since it was the same for everyone, I am sure somebody else must have written it in their interview experience.
Round 4

Behavioural Interview

Interview Experience
The third interview started with questions like why consulting, which other companies did I appear for, how did I fare, what went wrong etc. They also wanted to know if I had appeared for CAT or GRE. Then we moved onto the other HR questions about my aspirations, immediate plans etc. The case that I got was particularly interesting. The case was how to increase the revenue of my dads manufacturing unit (my dad has a hosiery manufacturing unit) by 5 fold in 3 years. This was also easy since I had all the facts that I needed before I even started. I didn't have to ask the interviewer for any clarifications or dig for any facts. So I started with increasing working hours to 2 shifts of 8 hours each. Then I would increase exports by exporting to Europe and US by manufacturing in summers and for African and South American nations in winters. Australia would not be a market as all the raw material mostly comes from Australia and it would be hard to compete with the Australian domestic manufacturers. Then an year or so later, I would look to launch my own brands and work a franchise model as I didn't have much experience with the retail business. Launching my own brand would bring much better margins. I also discussed the possibility of attracting brands like GAP, ZARA, C&A yet not available in India and manufacturing for the domestic market. I also discussed the possibility of entering the other segments of garment market as I had the required contacts & reputation in the market. All I had to do was set up new manufacturing facilities. The case was again followed with a couple of HR questions.
General Tips
Take things more seriously than we tend to in IIT Bombay. Especially for those preparing for tech and i-banks, study hard..

Also, do not write anything which you are not sure about in your resume because you may feel that it would be helpful for getting shortlisted but considering that your resume would drive your interviews so it is very necessary that you are confident about the things in your resume. Placement Experience (write in different section for different companies)





Final Tips :

Start preparation as early as you can. Decide what kind of work you would like to do and then decide what sectors you want to prepare for. Be in touch with the seniors who are working in the firms that you are targeting. Their advice would be very helpful. Also do some mock interviews in wing or attend the workshops conducted by SPO.

Interview Tips
Your resume should be at most two pages long and should contain everything about you but it must be to the point. You must be thorough with every line that is written in your resume. It's just a basic criteria which is generally met by everybody.
Round 2

Test

No. of Questions
45 questions
Test Sections
  • Section 1: Aptitude
Interview Experience
The paper consisted of objective aptitude questions. The main area of focus should be probability and combinatorics since it requires more practice than the rest of the topics.
Interview Tips
You should brush up your aptitude skills because every company that you sit in for has a section of it in the written or online test. You must not neglect it in any cost. Although the basic aptitude skill of every student is good, but what matters during the test is the speed and accuracy and that only comes with practice. The higher the marks you get in this section, the better are your chances to score higher than your fellow peers. Although the marks in the test are not the sole criteria for the result, but it does play an important role in your selection.
Round 3

Guesstimate Interview

Interview Questions
  • Question 1: One probability question
  • Question 2: Coin on a Round Table puzzle
  • Question 3: Guess the number of people watching a particular movie show in the United Kingdom
Interview Experience
This was the first round of four interviews that I altogether faced. The above three questions were asked to me serially. But before that, I had been asked to give a brief introduction of me. I had solved all three of them. The first question didn't take much time. Since I am not that interested in solving puzzles, I took some time in solving the second question but eventually I did it. The third question is a guesstimate. I started solving it with the inputs being given by the interviewer and I moved closer and closer to a realistic range as per the data inputs that were given to me.
Interview Tips
The practice that I did for aptitude helped me in solving the first question. That's why putting in a little effort in improving your aptitude skills will ultimately help you. The puzzle questions can be found on the internet and you just have to go through them once. After a while, you will be well acquainted with them and you won't face any problem in solving them. And for the guesstimate, the best option you have is Google. Surf the internet and you will get loads of them and how to approach them. They are the questions that are used to check how you approach a problem.
Round 4

Puzzle Interview

Interview Questions
  • Question 1: What is the 10 digit number a[0]a[1]a[2]a[3]a[4]a[5]a[6]a[7]a[8]a[9] in which i occurs a[i] times?
  • Question 2: There are 100 tablets (each weighing exactly same except for one). You have to find out the correct medicine by using a weighing machine but the catch is each time you weigh, it costs you 1 billion, How will you find one correct medicine by keeping the cost minimum?
Interview Experience
This was my second round in which I was asked only two question and both were puzzles. I could answer both but my approach in the second question was wrong first. The interviewer made me clear and then asked me to answer. After the questions, we had a conversation on my doubts regarding the work and the company.
Interview Tips
The puzzles as I already said can be practiced from the internet. But the most important point is you need to clearly understand the question before answering them. The second question was a conventional one but with a twist, which actually checks how attentive you are. So you need to hear and understand the questions properly. In case you do not understand in the first go, ask your interviewer to pardon again.
Round 5

Case Study Interview

Interview Questions
  • Question 1: A probabililty question
  • Question 2: Cement Industry in India
Interview Experience
The third interview consisted of a simple probability question and a case study. The case was a Cement Company in India that was losing its market share and I had to describe the reasons considering the constraints were given to me.
Interview Tips
You can easily get the examples of case study problems along with the ways of solving them, on the internet. The most important thing is you need to think out of the box of all the possibilities to analyze the case from an unconventional domain.
Round 6

HR Interview

Interview Questions
  • Question 1: The Three Door Puzzle
  • Question 2: General HR questions
Interview Experience
This round was taken by two persons simultaneously. There was one puzzle asked and the rest of the interview went on with general HR questions and answers.
Interview Tips
HR rounds are the easiest of all in the interviews of technical companies. You only need to prove what you say. There must be no contrast in what you speak and what you think at that point of time. At no instance of the interview you must contradict yourself.
