I received a take-home assignment from a GitHub bot with no prior engagement with any recruiter. I spent four hours on it and heard back the next day that they would like to schedule an interview.

I spoke with the recruiter, who asked about my preferred date for the final rounds. The next day, I received an email stating that the hiring manager would not interview me since I don't have three years of experience (YOE). LOL.

If YOE is such a hard bottom line, why send me the take-home in the first place? What a giant waste of time.

Design an API. This is pretty simple and googlable.

Make sure to exhibit good Git knowledge.
