The interview process
FB interview is divided into two parts, one is phone screen and the other is on site. I only had one round of interviews, four rounds of on-site interviews.
Interviews are all coding.
01 electric plane
I was a little nervous on the face, but I got it.
Coding: Implements circular queues with basic queue attributes
02Onsite
Onsite following the onsite interviews are FB’s Menlo Park headquarters. During the whole process, the interviewer seemed very nice.
However, I felt that their work was very busy. I met frequent phone calls during the interview, which greatly affected my thinking.
So it is also important to develop anti-interference ability.
01. Merge sort
Pure merge sort, no extra conditions.

4.Coding: Buying and selling stocks
I have done this problem countless times, lintcode has a total of 3 related deformation problems, I have done all, so it is relatively smooth.

The interview feeling
The whole interview down, feel the topic is not very difficult.
Perhaps the interviewer does not judge whether a person will succeed in the interview merely by getting the questions right, but by the qualities that a person can show if he or she gets them right.
Getting it right is a must anyway, so it’s advisable to scan LintCode before an interview.
