I applied through a recruiter. The process took 2 months. I interviewed at Meta in Jul 2015
Interview
So far have had 3 interviews and am going onsite for further interviews (I am an international candidate). First was a "general chat" lasting about an hour, including some basic technical questions about the Objective-C runtime. Second and third interviews were technical/coding challenges - an easier question and harder question. Coding is done in a shared online code editor. At every stage the recruitment contact has been *very* helpful, and the technical interviewers were also great to get along with.
Interview questions [1]
Question 1
Given two unsigned integer values, write a function that returns the first divided by the second. You cannot (of course) use div or mod operators - only addition, subtraction and multiplication. Discuss the strengths/weaknesses/algorithmic complexity of your solution. Is there a better way to do it? If so, what, and what is its complexity?
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.

Question 1
Given a string, determine if it is a valid palindrome considering only alphanumeric characters and ignoring case.
