I have a job interview next week for a full-time position. Problem is, I need this job so badly, but I'm going on vacation in july for 1 month! I'm paranoid of telling the employer about that in the interview in fear that he won't hire me. How should I go about this? I was debating on not saying anything until 2 weeks in advance or so...but should I even be honest in the interview or is that unnecessary?
