Good interview process. As an intern, you will have an initial screening interview from a recruiter asking about experiences in school etc. The main point of emphasis is to see how you work in groups, how you deal with setbacks, that sort of thing. If accepted, you'll be flown out to Dallas for an on site interview. There was a panel of managers and/or engineers (3 in my case), along with one HR recruiter. They will ask in particular to find out why you are a good fit for Southwest, and if you reflect the friendly and positive mentality of the company. You will certainly be asked to discuss how you work in groups, how you dealt with interpersonal problems, all of which requires examples. No technical questions were asked for engineering intern positions. Great interview process, you'll see very quickly how genuine and friendly people are within the company.
