First a team fit interview with a senior person. Some technical questions from resume followed by 2 ds algo question. One question on bitwise operator and next was around binary search.

I got a call from one the placement agencies. Had a telephony technical round with one of the members from the recruitment agency. This was fundamentally very algorithmic. Next I was given to implement cache in any language. I implemented in Java and sent it to them. This was accepted and my profile was forwarded to Amagi team. Had another telephony round with the engineering head of Amagi which lasted for 40 mins. This was also very algorithmic in nature. After the call I was called to their office. The same person interviewed me once again asking me to design a product on which I would suppose to work. This went well. Then I had a HR briefing on the company. I was then asked to leave for the day and asked to come next day for another round of technical interview. Had a long interview with one of the founders. Unlike the previous rounds, questions were around basic computer science concepts and system programming. Then they decided to offer me the job with fat cheque
