Just had a phone screen with META for SWE (not sure what level) in the US

First question was https://leetcode.com/problems/buildings-with-an-ocean-view/description/
Second question was https://leetcode.com/problems/top-k-frequent-elements/

I solved the first question pretty easily. But wasn't able to complete the second. I offered a solution with a dictionary and a heap, but seems he was only interested in the bucketsort solution.
I didn't get a chance to write code on the second question so pretty sure it's a fail. I hope this helps someone
