To be eligible for the internships, you have to complete the CFI course, then go throught the interview process and get put on 'the list'. When I went throught the interview process the majority of those interviewing were successful. It varied from month to month but was probably 70-80%. That was along time ago, so all I can say is ask around. After that you apply for the internships. You have to interview for this as well, but I don't think this is a big thing. I know of at least one person who was turned down by the center they wanted, but ended up going to another center. I think that if you apply yourself while you are here you will be ok. If you don't feel comfortable interviewing, the people in Job Placement will help you with mock interviews, etc.
As far as I know, there are 3 internships offered. One is the 90 day internship for students on the CFI wait list. You spend some time in various offices helping out, and some time in the Sim learning your aircraft. You also get qualified to teach 'enrichment' classes. These could be classes like high altitude operations, etc. You are supposed to spend a certain amount of time in the sim, so you will not just be an office slave. Usually at the end of the internship you end up with a SIC checkout. A few have gotten type ratings, but I am not sure if they are still doing this. I would think that they are probably not typing most student interns. There have been a few who have had their internships extended beyond the 90 days, and these would probably end up with a type rating after a year.
The second internship is for instructors done with their contracts and is for 1 year. These get typed. The only drawback is it pays $7.00 hr and is part time. I would only do this if I met ATP minimums, they you could get typed, and get the ATP at the same time.
There is also an internship offered with ASA airlines. It is like a traditional college internship. You get rotated among several departments for about a semesters worth of time. After you are done, if you did a good job, you are eligible for an interview at lower minimums, assuming they are hiring. Usually airline interns are a 'shoe in'. You are also usually expected to work for no pay and pay all living expenses.
