Stevie, dont worry about the 'interview'. My experience of that is its only there to see that you arent a complete gum nut and have the finance to back up your desire to be a pilot. I would advise against doing the degree part time because when you come out of school you really do need a few extra years life experience under your belt before you go looking for work. Generally operators dont want someone who looks like 13 years old flying their aeroplanes with passengers. So you may as well be doing something whilst you're waiting to look older
Of course there are exceptions and this is nothing personal because I dont know what you look like. Just remember, although its very competitive at almost every stage - its not a race. Take your time and do a job properly rather than do it half assed.
