My first round was a HR round. It was a very basic one. it lasted for 30 mins Questions asked: Tell me about yourself Salary expectations Resume Describe yourself in 3 words I cleared this round and went on the second round which lasted for 2.5 hours. The first 1.5 hours was all about scenario based questions like "Tell me about a time where the client could not understand you". The last 45 mins was about two puzzles. One where he showed me a object oriented class diagram and had 5 questions related to it. Another was a workforce scheduling question. He showed the quintiq software and asked to find an optimized solution. After clearing this round, I was called for the another round where I had gone to their office. This round was filled with customer puzzles related to everything you can imagine. UI questions, workforce scheduling, object oriented questions where he asked me to draw a class diagram. Then there were questions asked on C++ where they asked me to code. Then there 10 puzzles given to solve in 10 mins. These were more into logical reasoning questions. This round lasted for 2.5 hours. After this, there was a director round where he just wanted to see the fit for this role. It seemed very casual, he was more interested in getting to know.
