It was a 3 step process - 1) A written round - (Analytical and Technical questions) 2) F2F interview - Technical and puzzle round. 3) HR round - Its more of a formality than a round. First Round - Analytical Questions - The questions were from easy to average level. It tested concepts of angles, averages, AP GP , Time and Distance and other basic class 10 maths. Technical Questions - I was given an option to choose my Technical Paper ( C++/Java/Android). The questions were from easy to difficult but you don't actually need to answer all correctly. There is no negative marking and all questions carry equal weightage. So if you are able to do 70% of it you should be through. Second Round- I being a lateral hire was asked questions on my previous experience. I had to explain the architecture of the modules I worked in and also specifically mention my own efforts put in the work. I was asked to write two simple programs, one was on using Stacks and the other one was on creating a thread safe singleton class.Many other questions were asked as well to check on my eagerness to explore and innovate. Overall I had a very nice experience during the whole process.They are quite flexible and try to understand your strengths and where it can be it in real perspective.
