Paintzen Software Engineer interview questions

Not amazing. Went in for an on site, was told that two of the four people I was supposed to meet weren't there--one was sick, but one was on vacation. Ended up scheduling another on site...two weeks after the first one. Ok. I was left to chill in the waiting room on the second onsite for about 30 minutes before talking to the two people I missed. One guy was very nice; one was barely paying attention and seemingly purposefully unpleasant? Maybe this was a bad cop type of thing. Who knows.
