The OP mentioned in his original post that he told the other places he accepted a job offer and canceled his interviews. When he called back, they told him he needed to try again in three months. If you were at one of those companies, what would you think of an applicant who canceled a scheduled interview saying he'd accepted a job elsewhere and then called back wanting another shot? Right or wrong, they're going to assume the person wasn't very interested in their company to begin with. Lesson learned: Do not turn down scheduled interviews.
