I applied through college or university. The process took 6 weeks. I interviewed at Meta in Sep 2017
Interview
This was for a new grad position. Gave my resume at a career fair, heard back a few days later for an on-campus interview. Interview was fairly easy though I didn't think I did well, but heard back a few days later saying they wanted to schedule an onsite. Onsite was two algorithmic interviews and one behavioral plus a bunch of events selling us on Facebook. Algorithmic interviews were very standard Leetcode; interviewers were friendly. Behavioral was asking a ton of standard behavioral questions off a list. The guy very clearly did not want to be doing this interview and it was sort of uncomfortable. Got an expected rejection a couple of weeks later.
Interview questions [1]
Question 1
Leetcode easy-medium for the first interview and medium-hards for the onsites. Standard STAR questions for the behavioral.
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.
