I applied through a recruiter. The process took 4 weeks. I interviewed at Meta in Oct 2013
Interview
Received message via LinkedIn for an interview, shortly after replying a quick phone call was set up to determine what my interests were and how it aligns with the work available at Facebook. After that, a phone interview is done to screen candidates, the phone interview involves actual coding done using a shared online notepad. Then an in person interview is done which consists of 4 interviews (algorithms - system design - class design/algorithms - behavioral). There is also a break where you can ask an engineer any questions regarding the company. Results come back in a week after the in person interview.
Interview questions [1]
Question 1
signed NDA so cannot discuss. But do prepare for sorting, pattern matching algorithms, design problems such as how to go about implementing certain features in Facebook, and review previous work experience for some stuff to talk about in depth during behavioral interview.
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.

Question 1
Given a string, determine if it is a valid palindrome considering only alphanumeric characters and ignoring case.
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.

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.
