Applied for an iOS position - was initially contacted via LinkedIn. Overall really enjoyed the process. Was quite drawn out due to personal circumstances. Interviewed from Australia, initially a phone screening interview (5 fairly basic iOS questions, understanding blocks and ARC), followed by 2 technical phone interviews (algorithmic coding questions plus verbal conversations around past work experience and also technical iOS questions. After passing in these two phone interviews they flew me out to Menlo Park for a day of interviews. There were 5 interviews, one initial chat to warm up, talking about past experience, working relationships, etc, and a brief coding question on the whiteboard. There were 3 more technical interviews of same format as the initial phone interviews. Plus one interview on designing scalable iOS app architecture for a simple app. I really enjoyed the process and found the recruiters very helpful and friendly. Going and visiting Facebook HQ was great and as the reviews say all the people were great. Recommend doing for the experience. Getting an offer is tough. For me it came down to not being quick enough in answering the questions in the onsite technical interviews. They weren't overly difficult but they want you to move fast, and I tended to take my time and discuss with the interviewers which I believe worked against me. The other aspect was a general lack of experience (I have 18 months experience), and this reflected especially in the iOS design interview. Hope this helps others considering going through the process! I definitely recommend it!
