The recruiter reached out to me, followed by a call from the hiring manager. The HM referred me to another team.

Another recruiter reached out to talk about the team. A one-hour technical interview was set up. The communication was fast and professional.

The interview began with the problem description, which lasted for more than 10-15 minutes, only to reveal LeetCode hard questions. This was a colossal waste of time from the candidate's perspective.

They could have just asked to traverse a tree and print the end nodes.

The second part was to build the in-degrees and out-degrees of a tree, but it took me 10-15 minutes to understand the problem description. I had run out of patience trying to understand those diagrams and the long description.

It was an out-and-out topological sort. By then, I had run out of time.

To all the interviewers: Please state the problem in simple words. Candidates have a mere 45 minutes to code, execute, and debug test cases.

1. Print the last node of the tree.

2. Topological sort algorithm.
