Three interviews?? A bit overkill isn't it? One's enough IMO. You can assess everything you want in just one meeting. Any more is just a waste of time and resources.

Hair-wise, I didn't have anything in mind really. I guess I was just referring to different ways you can have it, like neat/messy, sleek+swept back or lifted and volumised, .....and stuff.

Meh, hope the application goes well though. Funnily enough, when I went to my job interview, they pretty much just wanted what hours you were available for, and you pretty much had a job. They might have been short on staff though. But it was a pizza place, so prior skill is not an issue.
