I got the interview on campus.

There were two coding questions. It went well, and I could solve the problems, even though I got stuck on explaining complexity and answered them incorrectly. However, the interviewer explained the correct answer and how to calculate it. I thought I wouldn't pass, but I made it and had to fly to Menlo Park!

The experience at Facebook HQ was great. The weather was nice, the people (candidates and campus tour guide) were nice, and the food was nice!

There was only one interview in the morning (I heard there were three rounds for full-time). It lasted 45 minutes and consisted of general questions and one coding question. I didn't do well on the coding one. I couldn't solve the problem and tried many ways to approach it. Finally, the interviewer gave me the approach to solve it and let me code. I didn't code well, though, making many mistakes.

After the interview, I had a tour around the campus. I was still shocked from the interview and thought I wouldn't pass... and I didn't.

However, I really had a great time at Facebook HQ. I thought about the question again, and it wasn't hard. I had to be more prepared!

PS. Don't take a limo! They won't reimburse you for that!
