CDCR Psych Eval too short?

How’s it going friends, I had my psych eval for corrections a couple weeks ago. For some reason, I thought It was going be about 2 hours long, but ended up being about 25 minutes to half an hour. I get that if it lasts longer than an hour than apparently there’s a bunch of red flags that they are trying to figure out. But what if it’s too short? Obviously, they know about my mistakes that I made when I was a teenager, nothing but misdemeanors though. I’m in my late 30s now btw, with no tickets or any crimes. I even got an education, a degree and a great trade. Pretty much turned my whole life around and have the credentials and life to prove it. Just wondering if anybody else has experienced a short interview and succeeded.
