I found the interview process very simple.
I had one hr round about company overview.
It was followed with a technical round - this is a good challenging experience.
I had next round with the CTO and this isn't as complicated as it sounds. He is more keen on knowing how you work rather than what you know (that's taken care in other rounds).
Lastly I had another round which was also technical, and far more challenging. I was given a scenario which was very realistic and they reviewed my code and testing.
Since I was an international candidate, HR team is constantly in touch with us to keep us timely updates. A big kudos to this team for always keeping one updated and being very very helpful.
