Meta | Phone Screen | Passed
Summary
I am sharing an anonymous phone screen interview experience with Meta, where three specific LeetCode variant problems were discussed. The candidate passed the interview and heard back after 6 business days.
Full Experience
Hey y'all, sharing a recent interview experience on behalf of anonymous. This ain't me but I hope these data points help. OP was asked the variants, not the OG - so, I linked the variant posts below.
Q1: LC199 Right Side View
Variant: what if you had to return both views, the left- and right side views? It was noted you can combine the two lists into one, rather than just using a singular list. So, there was no need to overly optimize here.
Q2: LC56 Merge Intervals
Variant: What if you had to merge two interval lists? The interviewer copied and pasted text that mentioned each interval list "containing intervals in ascending order. Merge them."
The interviewer had followed up with testcases for the candidate to go through.
...I can only imagine it was due to a lack of communication from the candidate's end. Or a lack of dry-running. Or if there were bug(s).
Q3: LC103 Binary Tree Zigzag Level Order Traversal
Variant: What if you had to return the order from right to left for the first level, then left to right, etc? It's the opposite than the OG problem.
There was time left so Q3 was given. Code was required.

I don't know information beyond this, other than the fact that the person heard back after 6 business days.
Good luck with your studies!
