I applied through a recruiter. The process took 1 day. I interviewed at Meta in Jan 2010
Interview
A technical recruiter set up a call with me. She asked about my research projects which she can't care less about. Then she asked what programming languages I am most comfortable with and some specifics about the language. I was also asked about the runtime complexity of binary search and the average num of guesses it takes to find a number between 1 to 1000. Overall it's pretty simple since this is just the first screening. The next interview will involve writing code in real time to solve a question asked by an engineering on the phone.
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.
