I applied through a recruiter. The process took 2 months. I interviewed at Meta in Nov 2016
Interview
I was contacted by a Facebook recruiter to set up an interview, after having dropped my resume for the company at a tech conference. Had one technical phone interview that went well and was booked for another interview. The second interview was okay, but I was given a third phone interview and rejected afterwards.

Question 1
Given an encoding of numbers to letters (A: 1, B: 2, ...), determine how many ways you can decode a string of digits.
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.
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.

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.
