I applied through a recruiter. The process took 5 weeks. I interviewed at Meta (Menlo Park, CA) in Dec 2016
Interview
I contacted a recruiter via email that I received by a former Facebook employee. She followed up asking some standard questions about my experience and availability with a phone screening that lasted about 15 minutes. I then scheduled a phone interview with an engineer in the Instagram even though I was only applying for positions in Europe. The question was pretty difficult and it was more of a mathematical problem than a computer science questions. I studied a lot of algorithms and data structures exercises. The engineer helped me getting the idea on how to solve the problem but I was running out of time unfortunately.

Question 1
It was a mathematical questions about finding the greatest number (but less than the given number) by reordering the digits in the number.
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.

It's honestly striaght from leetcode tagged
There are no surprises if you do tagged you would be good and do well.
System design is much harder. Would recommend using hello interview.
