I applied through college or university. The process took 2 weeks. I interviewed at Meta in Mar 2015
Interview
Interview was for software engineer. I got the interview call through career fair at campus. It was a telephonic interview for 45 min. The interviewer was very polite and helpful. In the end I messed up things. It started off with the interviewer introducing himself, and asked to introduce my self. Then some behavioral questions, like why Facebook, which team, either Front-end or Back-end are you interested in, and a couple of questions on my projects and resume. The interviewed happened on a Thursday. At the end of the interview, the interviewer told "Sorry! Time's-up". Then itself I understood, I would not clear it. Next monday, I got a mail from the recruiter, that they can't move forward.
Interview questions [1]
Question 1
You have a string that consists of all types of characters, alphanumeric, special, uppercase and lowercase. The string should still tell me that it is a palindrome or not. For example: 12@#.Race@#car. The example is a palindrome. (Omit the special characters, and do not consider the string to be case sensitive). I wrote the code in O(n), but I was using an extra string to store only the letters. The interviewer asked me to do it in place (use only that string and check for palindrome)
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.
