I applied through a recruiter. The process took 2 weeks. I interviewed at Meta (Seattle, WA) in May 2015
Interview
Met recruiter at the Facebook offices, she showed me around. Because I was applying for an engineering position, it started on the engineering floor, which isn't too big. Nice offices but nothing super special, she did mention they were moving fairly soon. After the brief tour went down to the 2nd floor and went to a small room for the technical screen. An engineer came in and for a minute or two asked me about my background and work experience. Then went and asked me two technical questions. The first one was pretty straight forward, but I spent a long time explaining my thought process and debugging and everything. (As a ton of sites say you do). Second one was a bit more of a puzzle question and stumbled a little on it, basically it was a binary search algorithm. Unfortunately a miscommunication at the beginning of the question caused me to try to think of it in a different direction, but eventually got it and realized time was up so I quickly coded the solution and debugged it, but didn't explain myself probably because I knew the time was up.
Ultimately got both questions right with a minor stumble and then was not asked for a further interview, so I really have no idea why, and unfortunately I understand for legal ramifications why they can't tell me. However not getting past the screen was unexpected.
I applied online. I interviewed at Meta (Menlo Park, CA)
Interview
It's honestly striaght from leetcode tagged
There are no surprises if you do tagged you would be good and do well.
System design is much harder. Would recommend using hello interview.

Question 1
Design Twitter and consider if it was suddenly an extremely low latency env
Grateful doesn't even begin to describe how I feel about landing this role. The interview loop was smooth and friendly. They kicked things off with a technical round where I faced a DSA question about verifying an alien dictionary. Lucky for me, the time I'd spent on PracHub paid off, as it had the same type of problem just days before. After that, I had a system design discussion and a behavioral interview. Everything felt very collaborative, and by the end, I received an offer that I was thrilled to accept.
Interview questions [1]
Question 1
Given a list of words written in an alien language and the order of letters in that language's alphabet, determine whether the words are sorted lexicographically (Verifying an Alien Dictionary). Walk through the comparison approach using a character-to-index map, the O(C) time complexity where C is total characters, and how you'd extend it to handle words with mixed-case letters or words containing characters outside the given alphabet.
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
