I was interviewed on-campus
at IIT Bombay for
Resume Shortlist Test Guesstimate Interview Technical Interview Stress Interview Behavioural Interview HR Interview
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).
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.
No. of Questions
- Section 1: Objective
- Section 2: Subjective
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).
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.
- Question 1: Write a 10 digit largest number with some constraint (I didn’t remember the exact constraint but it’s a standard question)
- Question 2: Guesstimate the number of viewers to a sports blog
The interviewer first goes through my resume and ask some basic question, not in depth. Then he asked me some puzzle (similar type of question asked in the subjective paper but with a high level of difficulty) and one guesstimate.
My interview last for 10-15 mins, the interviewer is very helpful and always try to calm and comfort me.
The interviewer gave me feedback and point out some area on which I can quickly look it for further interview.
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.
- Question 1: How to assigning the new task to employees based on their past performance.
- Question 2: Some Probability problems
Next round was the telephonic interview with a senior analyst. The interviewer asked me some question from my resume especially on the technical project which involves some mathematics tool.
Then he asked some probability problems which are very tough.
The interviewer was interested in your approach only, how you’re tackling the problem. How much wide can you think? The interviewer is also ready to help you and try to figure out your strength. So be calm and speak with confidence.
- Question 1: Guesstimate how much a thief, who operate on shopping can earn in a year
- Question 2: The probability of a car passes the highway in a subset time if the probability of a car passing in one hour given.
The interviewer asked me some question from my resume in depth.
He asked one guesstimate and one probability question.
The interviewer started with questions like why this company, which other companies did I appeared for.
He asked me some quick calculation problems.
- Question 1: Some basic HR questions
