I was contacted by a recruiter.
I finished my assignment over the weekend.
I had a phone interview with the tech director, who seemed to like the assignment's result. The questions were pretty straightforward.
The recruiter emailed me about an on-site interview.
Then, the recruiter called and said another tech lead wanted to do a phone screen.

When I followed up again, I was told the tech lead wanted someone more senior.
