Phone call with the hiring manager (skipping the recruiter), and then a take-home code test. They asked for the code test to be completed within a week.
Once I submitted the code test, it took a week before they responded that they had received it. After that, I never heard from them again, despite following up several times. While I'm surprised that my code test was not enough to move me to the next round, I'm most disappointed that they didn't have the courtesy to at least respond. In my view, taking hours to complete a code test for them deserves a polite response of some kind, even if it's a rejection.
