NV5 interview questions

I applied online and then got an email for a video interview on Teams. The vibe of the interview seemed mundane. But the kind of questions they asked were decent. The basic behavioural questions and then they moved on to the technical questions which were not in my resume but in the domain I studied. I wish they'd smile or make it friendly a little more because the vibe wasn't exactly helping me feel any more comfortable and relaxed. And now I can't judge if it went good or bad and am still waiting for their response.

I applied online through their career website. A recruiter reached out to me after a day or two asking for my availability for a phone screen. I emailed her back but I didn't get a response. I sent her a follow up email but she never got back to me. I know a few people in this company and I've always heard good things. That's why I was very interested to apply but to be ghosted by one of their recruiters is so disappointing. I hope their HR department does a better job and train their employees properly.
