Interview questions [1]
Question 1
You are given an integer array nums and an integer k.
Return the length of the longest subarray whose elements sum to exactly k.
The subarray must be contiguous.
nums may contain positive, negative, and zero values.
If no such subarray exists, return 0.
I applied online. The process took 3 weeks. I interviewed at Meta (Redmond, WA) in Oct 2024
Interview
3 interviews, each with a software engineer asking me to implement functions in python. Like implement a convolutional layer. The questions were not difficult; there were some trick questions in terms of knowing you can find the median in O(n) with quick select, as opposed to O(n*log(n)) with sort and grab the middle element.

I applied through a recruiter. I interviewed at Meta
Interview
Typical 2-3 leetcode questions to complete in 45 minutes with edge cases and working code. Its based on luck if you get what you already prepared. Just go through top fb questions and hope that they ask you from that list
