A major (Super Bowl advertising) SaaS vendor sprang a single Leetcode interview on me after an informal discussion with a VP, it was introduced as “have a chat with senior engineers”. I take 30 mins to solve it. The company they ghosted me, despite my having 3 former colleagues in the same division I was interviewing in. Eventually one of my former colleagues divines that they were disappointed it took me that long. Definitely happens. Checked my solution at Leetcode, top 5% of performance in Java.
