I applied through an employee referral. The process took 2 weeks. I interviewed at Meta (Menlo Park, CA)
Interview
It all started with a mail, I applied online but they noticed me through the recommendation of someone that already works at Facebook.
A week before the online interview the recruiter called me through Skype and explained the process.
The interview was held through Skype (No cam) and I coded using codepad.io.
Interview questions [1]
Question 1
They asked me to do a recursive function of a powerset (Ex. powerset(a,b,c) = ((),(a),(b),(c),(a,b),(a,c),(b,c))
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.
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
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.

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