I had a good conversation with one of their technical recruiters, after which I was given a coding challenge which requested I spend no more than 2 hours on it.
I put in the time, submitted a link to the repository, and received an email stating they would not be moving forward with my candidacy. I replied, politely asking if they had any feedback, and was ghosted.
If a candidate puts 2hrs into a coding challenge, the least you can do is take more than 2 minutes to compose a canned reply.
