I applied for a general mechanic posting in Chicago that stated you could be employed at another bases depending on how the interview went at the hiring managers discretion. I received an email saying i was being considered for employment. A couple days later i was contacted by phone and told i had an in person interview the following week and had to choose between 3 days. I went did the interview they told me i got the job but the official offer letter would not be sent till about 3-4 weeks later.
