So I got a 2nd interview for an internship with the company tomorrow at 9AM PST but I have a problem: I just realized that I can't accept the position because of scheduling conflict with school. Should I... 1) Be upfront with the interviewer when I go in for my interview tomorrow (i.e. tell the interviewer my situation and thank her for her time. Keeping it brief.) OR 2) Go through with the interview process, see if I get hired, then decline it if I get hired. I don't know what the professional way of handling this situation is. Please help! TIA!
