I was hired on e for a position at a 35% pay raise; while this isn't particularly unusual in tech, on the first day, I couldn't figure out what they were talking about with most things. They couldn't figure out why I couldn't figure out their setup requirements. After almost 8 hours passed, they said they switched resumes on accident... so I'd quit my last job for this job, worked there a day for no reason, and was back on the street. The previous employer wouldn't take me back, and I had to start over.
