I applied through a recruiter. The process took 2 months. I interviewed at Meta (Menlo Park, CA) in Mar 2015
Interview
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!
Interview questions [2]
Question 1
An interesting exhaustive phone number pad permutations question. Eg, if you touch one number on a keypad and then drag it around the keypad (horizontal and vertical movements only, no repeats), enumerate all the possible words you could create. These sorts of questions are common.
Took about a month altogether, which felt longer given the intensity of the process. Kicked off with a technical screening, followed by two rigorous coding interviews. The DSA question on binary tree vertical order traversal hit me hard at first, but then I recognized the prompt instantly — I had just worked through something similar on PracHub. The final round was focused on system design, and while I ended up receiving an offer, I ultimately declined it. Overall, a challenging experience that definitely sharpened my skills.
1 leetcode med, 1 leetcode hard. make sure you know your DSA and leetcode questions. I wasn't able to get an offer bc i didnt complete the second question. Got a reply 2 days later saying they would move on
Overall, the process took a little over two weeks, which felt a bit longer than I anticipated. After a quick screening, I went through two technical rounds focusing on coding and DSA concepts. One of the questions was a classic palindrome check; mid-way through, I realized it was something I had practiced on PracHub just days earlier. The final step was a casual behavioral interview. I was relieved to get an offer shortly after, which I happily accepted.
