The process began with a 30-minute call by a recruiter. All positions were remote.

I was given a 4-hour timed assignment to complete on my own time.

I was rejected, and they could not elaborate on the reason why. It was a canned response: "We had many other great candidates apply." This was disappointing, especially considering there was an ambiguous requirement with no opportunity to ask clarifying questions. I felt there was more than one way to implement the requirements, and depending on the chosen route, the outcome could be a hit or miss. It seems they were looking for a specific answer.

Your time means nothing to GitHub, and many other companies, until you are hired. This speaks volumes about a company when, after joining, the emphasis is on "we live and breathe our core values and value everyone."

On the plus side, it wasn't a multi-day assignment, and at least they bothered to reply.

Was asked to create an API solution (CRUD) that can handle multiple parallel requests.
