Schulman Associates IRB interview questions

This was one of the most intense interviews I have ever had. The people seemed nice enough and responsive throughout the whole process. It became redundant though, when each person I interviewed with only had a couple questions and then spent the rest of the time (anywhere from 20-30 minutes) asking me if I had any question for them. While I did have some questions, filling that amount of time with them was pretty ridiculous. By the time I got to the last person, I had to dig to try and think of a question or 2, then felt like I was being judged for not having questions. So... basically prepare enough questions to fill an hour and spread them among each interviewer. I received and email about a week or 2 later letting me know that they had chosen other candidates. I appreciated their response whether positive or negative in respect of the time that I gave for an interview, however, after my interview I reached out in an effort to gain more information on why I was not chosen and asked for anything I could work on to improve in the future. I received no response. Everything before this was immediate, quick response time. To me, their attentiveness after a potential employee has been turned away says a lot more about this company than how they treat potentials. It is a struggle to get a job with little experience and I needed all the help I could get to keep improving myself and my resume, interview answers, etc, but Schulman IRB offered me no help.
