After applying online, got a response back from a recruiter. Took 2-3 times to get on initial call. First, there was miscommunication on availability. Then, recruiter went on a two-week vacation, said we'll be in touch afterwards. I almost forgot about them when I got a call back to talk about the opening. First step went well. Got to next step to talk to dev manager. Went well. Got set up to talk to one of the engineers on the team. Got on a call. Talked for about half an hour. Everything went well. Was told to expect an email with a link to an exercise. Never got anything back, not from the engineer nor from the recruiter. Emailed recruiter a few times, never heard back. At least some kind of a response would be nice.
