I applied through an employee referral. I interviewed at Meta in Oct 2016
Interview
It's a 45 minutes phone interview by a software engineer. He asked two questions about general coding. The questions are not too difficult, but there are some corner cases that are hard to be completely correct for the first time. The time is also a little bit tight.
Interview questions [1]
Question 1
The first question is two find the largest and second largest value at each level of a binary tree. You don't need to return all values, just print out instead. the second question is to return a value in an array with the probability proportional to the weight of the value within the array. For example, in an array [4,5,6], return 4 with probability 4/15, 5 with 5/15 and 6 with 6/15. You are given a function that returns a random real number between 0 and 1
The process is straightforward and designed to help us get to know each other. It moves through a few stages at a comfortable pace, involves conversations with several team members, and focuses on making sure it's a good mutual fit.
I applied through a recruiter. I interviewed at Meta
Interview
Had an initial recuriter call and then scheduled a coding round with 2 leetcode questions. Practicing Meta-tagged leetcode questions would help prepare for this round. Interviewers expect clear communication and code.
Generic LeetCode-style questions, many tagged as Meta, so extensive preparation is required to perform well in the technical interview. The experience varies significantly - some interviewers provide hints and guidance, while others expect candidates to solve problems independently with minimal assistance.
