I applied through an employee referral. I interviewed at Meta
Interview
1 recruiter screen, 2-3 rounds of technical interviews, and 1 final 4-5 hour behavior interview. The tech interviews were okay, mostly just asked to implement data structures and use various algorithms.
Interview questions [1]
Question 1
Find the most efficient way to sort through this array, and then explain its time complexity (Was one of the technical interview questions)
