re: I had an interview today where I THOUGHT I looked like an idiot about something

I interviewed for a programming position and during the interview I had to write a short code for a specific task.
I wrote the code but the interviewer, who is the head of the department, reviewed but didn’t run the code.

I got the job and about a month later, during a conversation, he told me I didn’t get the code right and it would error out. I knew it was correct so I wrote the code again then ran it. Sure enough the code ran without errors and produced the correct result.

He didn’t say anything or even make an acknowledgment.

Hated that job and left after a few months.
