I really can't think of any.

The company proactively invited me to an interview.

Before the interview, I was asked to complete an intelligence and logic test.

After I finished it,

I was told that the interviewer was still in a meeting. (It felt like the interviewer had no sense of time and did not respect the time originally scheduled.)

They simply asked me to wait.

I waited a total of 50 minutes before the interviewer finally appeared.

The interviewer did not seem to intend to apologize for the long wait.

The interviewer's tone was also rather arrogant.

Then I felt that the HR representative had not carefully read the résumé I had worked hard to prepare.

After asking a bunch of questions that were not very professional,

they finally said that the company currently did not have a position that matched my expectations.

Then why did HR proactively invite me? Why ask me all those questions?

I felt that the interviewer was not very professional.

It was truly a waste of time!
