I had a call with a recruiter, then a tech screen, followed by an on-site. Everything was fine, but the preparation was poor.

My main issue is that they claimed I would be working on "similar, everyday problems" in the technical portions. However, the truth is that I was still solving LeetCode-style problems with hidden data-structure solutions underlying them. 'Merge ranges' was obvious, and I was literally building a tree data structure from the ground up.

It's the same as most other large tech companies in the sense that generic LeetCode practice is valued.

1. Tech Screen: Build a search input field with React that communicates with an API. How would you optimize it (throttle, cache, etc.)?

2. Build a filter search function given a list of dates. This is very similar to merging ranges.

3. Build a class-based Tree data structure. (This is a very generic LeetCode problem; I wanted to walk out the moment I was given this problem.)

4. System design a CSV upload/save API. How would you store CSV files, and how would the client upload and retrieve those files?
