Long interview process.

Recruiter screen, manager screen, code review take-home (I spent 1.5 hours).

Then a final loop with system design, coding (1.5 hours), and 2 behaviorals.

The managers I talked to were great, but none of the engineers seemed engaged at all or like they wanted to be there.

After the final loop (which I thought went well), I was ghosted by the recruiter. He didn't even respond after I followed up a couple of times asking for status.

It's unacceptable to not even get a generic rejection email, considering all the time I put into this interview process.

Complete waste of time.

Coding - Download a real codebase with a Slack-like chat app using a SQLite DB. Had a list of prompts to add a feature (private channels).

System Design - Design a system to ingest commands/keywords given in Slack messages and call 3rd party APIs based on them.

Behavioral - Mostly standard questions. Also asked some vague open-ended technical questions, like "How would you think about the API for user search suggestions in Slack?"
