I went to the open house in SLC about a month ago. There were not very many people there when I went. Primarily they will show a video, to get you excited about working at skywest, tell you about the company and its plans to grow in the future. They will tell you that the mins are 1000 and 100, but the competitive mins are 2500 total and some turbine time. Depending on how many people are at the open house with better qualifications she can expect the option for a full interview. They offered me a full interview on the spot and i had 2500 and 500 multi, with some 135 experience, and no turbine time.
They are looking for people that they can put right into the CRJ.
PM me if you have specific questions, I have a few friends that work for skywest, i may be able to get some answers to specific questions you may have.
