I first received a call from an HR executive who went over a few basic questions about my current status, visa requirements etc. She then asked me things like - how would you deal with stress etc. This call was followed up by a call from the receptionist at the office informing me that I had been set up for an interview with one of the managers. The actual interview was thoroughly technical with difficulty of question ranging from trivial to fairly difficult. The emphasis seemed to be on prior projects and experience
