I applied through an employee referral. The process took two weeks.

I completed a recruiter screen, a hiring manager screen, and a take-home challenge. At the end of my call with the hiring manager, I was told I would complete the next step, which is a take-home challenge. I was asked for my GitHub username and sent the challenge the next day. I worked on the challenge over the weekend and submitted it on Monday. On Tuesday, I reached out to the recruiter and was immediately sent a rejection email. When I followed up and asked for feedback, I was ghosted. The hiring manager recently shared in a Slack group that they are still hiring for the role.

What is the most technically challenging project you have worked on?
