I applied through employee referral and pretty soon the recruiter contacted me and scheduled for a Skype interview. I think the process was pretty fast. The skype interview took about an hour and we talked little bit about iOS technology and finished with problem solving question. After that they invited me to onsite interview. The onsite interview was 3 round and each round was for 1 hour and 2 engineers was coming to interview. First round problem solving, second round design question and 3rd round was to about find a solution to uncompleted problem. At last after 3 rounds, I met with the CEO for a half hour. Over all it was very good experience. The team was kind of collection of top universities graduates.
