Interview Preparation Tips

Round: Test
Experience: The aptitude test consisted of about 20 questions and had just 20 minutes. The questions were tough and you need speed to solve them. People preparing for CAT and other such exams should be able to perform better. The max score among my batch was 7 or 8.
The coding question was paper based and you had to write C code for a simple question on paper, but design was also taken into account for evaluating the code.
Tips: Both get disheartened if you don't do well in the aptitude.
Duration: 60 minutes
Total Questions: 21

Round: Technical Interview
Experience: The interview was more like a discussion rather than a question answer round. The discussion always went quite off the topic and the interviewer went on to ask other concepts of OS and networks etc.
Tips: Be thorough with the core concepts in subjects like OS and networks

Round: Technical Interview
Experience: This interview was a little more of marketing PayPal to me than an interview. He however slipped in the questions given above. The machine learning question was a little too obvious to apply thresholding and I wasted time trying to get better algorithms when he expected only thresholding.
Tips: Do not tell you are the topper if you are, because I did and he clearly said they don't hire toppers!

Round: HR Interview
Experience: This interview was more to get the truth out of me. I have a very research oriented profile and that was evident from my resume. The interview was to find out whether I would really join their company if offered.
Tips: If you have a high CG and research experience but still want to go for a job, make sure you tune your resume to prune out the research and only market the side which the company looks for, otherwise the company will reject you.

Skills: Computer Science Concepts, OS, Networks, OOP, Machine Learning
College Name: IIT HYDERABAD
Motivation: Just as a backup since I was indeed planning for a masters program. Highest paying package among the companies at that time.
