T2 Systems interview questions

I applied online and got a phone screen. The phone screen went well according to the recruiter and I was told I was going to be passed to the next step. Then what is all too common, ghosted. I sent three follow up emails to the recruiter and didn't get a single response. Everyone understands if they don't get the job, it is the disrespect for time and feeling while looking for a new job.

There are 3 rounds for the interview. Behavioral interview with HR (under 20min) then Hiring Manager for technical questions( around 1h), last round (around 40 mins) a round table interview regarding past experience and hypothetical scenarios.
