I have been interviewed quite a few times and I interviewed a few also. Selecting a few out of a hundred was a pretty difficult task. But I think the most difficult was to listen why they wanted the job - so many of them had no idea what the job was about.

It is important to be dressed properly, to have the proper make-up, and so on, and I try to stick to these rules when I am being interviewed, but I have to say that the most un-professional and the worst colleage I've ever had (who I was against hiring) had everything a good candidate should have: proper outfit, proper hair colour, good looking CV, she even had a Master's degree, but boy she was stupid! And lazy! And apparently very impolite. So, keeping this in mind, I will try to give people a chance to open their mouth. The one she was hired over was dressed a little too "pretty" (she was another employee we had at a lower paid job), and anyway she kept doing a big part of the job of the "proper" one. How's that for a lesson how to dress for an interview?
