No response from interviewer

What should you do if you email the interviewer assigned to you to request an interview but get no response?

How much time has passed?

Just over a week.

Might be on vacation. Wait a few days

I think it took 2 weeks for my son to be contacted and then the interviewer wanted to meet less than 24 hours later. She said they have a separate account they have to log into to see their interview requests and that when she was busy she didn’t check hers.
