Viz.ai interview questions

I had an interview with two friendly interviewers. They asked me about myself and my previous work, introduced themselves, and then moved on to ask me technical questions. they showed me the system and explain it

Initially, they were responsive and I was able to schedule the screening interview quickly after the recruiter reached out. The screening interview was odd in that the recruiter didn't really provide any additional details about the role or company (despite me asking) and just launched into the interview questions. She also gave off energy that didn't make me feel comfortable asking any of my own questions at the end. Afterwards, the recruiter ghosted me and never reached back out again despite me sending two follow-up emails. Even a generic "no" email is better than not hearing anything at all. Overall, the process was off-putting and a little unprofessional.
