First had Friendly (possible) collegues, friendly atmosphere, semi-open enviroment, and the interviewers felt like they care about me and my personality.
The other one felt like a prison on a glance (there were even doors which could open only form one side…), and I felt that way the interviewer just see us (cuz it was a group interview) as an other plus one worker… (yeah, it was a way bigger place as well, so I understand it’s way harder to make personal interviews, but still.)
