I applied through a recruiter. The process took 4 weeks. I interviewed at Meta in Oct 2023
Interview
Had go through 2 rounds of screening, and then a full round of interviews (2 more rounds of coding, system design, and behavioral). The behavioral was run by an interviewer who was not fluent in English and hardly paying attention, and the horrible communication between the recruiter and I felt like I was being set up to fail this. Overall, felt like a huge waste of time.

Question 1
Because I had to go through 4 rounds of coding, there were 8 questions total, and I don't remember all of them. Of them all, I remember: least common node in binary tree, sliding window question, no DP. I got asked the LRU cache question twice, they really like that question
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.

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.
