The time frame in which you should follow-up depends on what, if anything, the interviewer told you during the interview. If they said that they hope to have a decision in two weeks, for example, then follow-up with them shortly after two weeks has passed. If they did not specify a time frame, I think it is reasonable to follow-up with the interviewer a week to 10 days after the interview took place. For the first follow-up, I would recommend an e-mail. If they do not respond to you within another week, follow-up with a phone call. The key is to find that balance where you are sending the message to the employer that you are very interested in the position, but not annoying them. Keep in mind that it is quite common for other priorities to come up for the interviewer(s), forcing the hiring process to the back burner.
