The last thing you want to worry about is what to do with your hair, when you have class or work to get off to. I would suggest that you go ahead and get the box braids for the simple fact that they are so versatile, that you could still pull off any professional looking hairstyle with these braids, pull them back into a low bun and good luck on your interview!! they are sure to give you the job based on your skill and not your hair!
