One written technical, one technical with lead and then HR. First they did he basic screening with objective written test, that was technical, mostly output questions and a few related to iOS concept. The technical detailed round for like 45 mins with tech lead. He asked in detail about iOS apps, from current project and new features of swift. AFter clearing this round there was HR round where they discussed expected salary and all. They told there will be one client round as well. BUt that round never happened, they did not call any of the shortlisted candidates(as few of us were in contact after interview). When tried to reach the HR, they did not even pick the call. I believe project might have stalled or something since they froze the process but they refused to communicate this thing, that is pathetic.
