I'm going to ruin my job interview.
Is that something that you want to do?
I hate to be interviewed.
If you don't want to be interviewed, I would call the company and just cancel the appointment instead of wasting their time. You don't want people leading you on just to find out they're not interested with you, do you?
I don't know, I might get them for wasting my time.
I think that you should just save everyone the trouble. It is not okay to go if you are just going to waste there time.
