Postition - iOS Engineer, London (E4 or E5)
YOE - 5

Done with my onsite this Friday.

[R1: Coding] - 2 standard questions, not from LC though. Did well, was able to run test for the first question but wasn't able to run for 2nd due to time constraint, interview said it's fine.

[R2: Coding] - 1 Medium and 1 hard question, was able to solve both in O(n). round overall went well.

[R3: Bahvioural] - Standard behavioural questions for challenging work, motivation behind joining facebook and so on. This round also went above average. I was able to quote past examples from my career to answer the questions.

[R4: iOS System Design] - Desing messanger app, the round went great. Was able to discuss multiple approaches for each compnent with tradeoffs and scalability.

My Pre screening happend in March this year and onsite was schedule for Oct because of the hiring freeze for E4. My rounds went well, might get E5 as well. Wish me luck!

If anyone have any update on FB hiring freeze, please comment. Would be really helpful.
