They start with technical interview after the HR introduction about the company. They slowly get in to deep in to what you have done in the projects I have worked on. As it gets more deeper, the questions are grilling. Once we clear this, there is a manager level interview and that is equally grilling technically. Unless you are hands-on, it will be difficult to get through.

The interview process went on for 2 weeks. 1st round- Technical round I was asked few questions related to my project, then basic questions about multithreading, multiprocessing, oops concepts, exception handling, data structures. The discussion went on for 1 hour. 2nd round - Puzzle and coding round I was asked around 7-8 puzzles out of which I could answer 6. It will be easy if you prepare on basic logics, puzzles from the internet. I was asked to reverse a string and some basic logics. The process went on for 1.5 hours. The 1st and 2nd round were completed within two days. After a week, I was asked to submit the documents. The next day I had my HR round where I got pretty much expected salary.
