Round: Resume Shortlist
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).
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: Test
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).
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.

Round: Resume Shortlist
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: HR 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: HR 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: HR 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.
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.
