The company isn't very large, and the environment is okay.

They needed a second interview but didn't mention it beforehand. The only person who interviewed me was an HR representative who didn't understand anything, which was extremely disrespectful to the interviewee.

The HR representative talked a lot of nonsense, going on about irrelevant company history and wasting a great deal of time.

They kept asking questions without getting to the point, while constantly doubting whether the interviewee could program. Did they think all interviewees were useless?

(If I couldn't program, why would I apply for an engineering position?)

Personally, I was pretty upset, so I talked back. I won't say what I said (P.S. If you want to join the company, don't act impulsively. I had already received an offer from another company, so I wasn't considering them). In the end, I also told them not to notify me about a second interview—it would just waste my time.
