Recruiting is a bit of a mess. Likely to send a rejection letter then follow up some weeks later with an invitation for an interview. Actual interview is very easy if you know what you're talking about and avoid relying on Google and Stack overflow to do your job.

I applied on their website and received a quick response. After a simple phone screening, I was invited to a local meet & greet and took a technical assessment. Then I was scheduled for an in-person interview. The first round of interviewers was normal, but the second round seemed unprepared and disinterested. One interviewer seemed almost distrustful and questioned very basic statements I made, such as that I like helping people. Whether this was intentional/standard fare for candidates or he actually didn't believe me, I couldn't tell, but it was certainly off-putting in contrast to the politeness of the other interviewers. A couple of times they asked the same, basic questions I had already answered in the first round. At one point I was asked if I had any certifications, despite them being on my resume in front of them. Overall, I got the impression that they look for very particular personalities above everything else and weren't interested in me from the start. After the interview, I was told I'd receive a response within 2-3 days. I had to reach out to the recruiter for them to immediately tell me they'd chosen another candidate.
