I applied online. The process took 2 months. I interviewed at Meta (Palo Alto, CA) in Jul 2011
Interview
Phone screen, Excel test, phone interview, skype interviews, 30 page assignment, flew out for on-site interviews, more phone interviews, flew out again for on-site interviews.
They put me through the ringer before they hired me. But the questions were relevant and the people I met were great. This was back in their Palo Alto offices though.
Interview questions [1]
Question 1
Pre-IPO, they asked me to write a paper on the valuation of Facebook. They also asked me what I thought the greatest technological advancement was in the past 20 years.
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.
