I got a chance of phone interview with Facebook through Interviewstreet about a year and a half ago and failed quickly, mostly because I'm not a native English speaker and I am really bad at speaking English. I keep practicing English after that, then I got another chance 2 months ago, recommended by a friend interning at Facebook.
The recruiter return to me very quickly, in less than a week, but I'm very busy and not well prepared at that time, so I did the phone interview a month later. I was asked to solve an easy coding problem, I finished it very quickly but made a small mistake in analyzing the complexity. I only found that mistake after the interview. The interviewer is very experienced, I have a great time talking to him after the coding phrase.
Then I got a chance to onsite. I had 3 interviews. 2 interviewers asked coding problems and 1 asked coding problems and also talked about my projects in resume. The problems are harder than the problem in phone interview. I really struggled at 1 of them. But I think I did a good job at another ones. The interviewer who talking with me about my projects is from a strong background and seems a little tough, I must say I was very nervous when talking to him, but luckily it turned out well.
In overall, the recruiters and the interviewers are all very nice. I am not familiar with the process of interviewing with companies in U.S and asked so many questions, the recruiters replied very quickly.
Took about a month from start to finish, which felt longer than I expected. After a couple of initial phone screenings, I faced a challenging technical round focused on system design. It was during this round that I was asked to describe overcoming a major career challenge. Interestingly, I had just reviewed a similar framework on PracHub, which helped me articulate my thoughts clearly. Overall, I appreciated the depth of the process and ended up accepting the offer.

The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.

Given an array of integers and a target value, return the indices of two numbers that add up to the target
Unexpectedly, the first question in the technical round felt familiar. It was about finding a subset of strings with unique character concatenation — same problem I had worked through on PracHub a few days earlier. The interview included a recruiter screen followed by a rigorous pair of technical interviews where I tackled data structures and algorithms alongside system design concepts. After successfully answering a few more challenging DSA questions, I received an offer. The entire experience was intense but ultimately rewarding, and I happily accepted the position.

Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
