If canceling job interviews once a person received an opportunity elsewhere is awkward, rescheduling a job interview is worse.
The reason for rescheduling can be many, and can range from illness, familial commitments, the inability to take time out from a present job, or appearing for another interview elsewhere.
Si, how do you reschedule a job interview?
The best approach in such situation is to stick to the truth as far as possible. If the reasons are genuine, nothing but the whole truth should be offered. If the rescheduling is to attend another interview, one good approach is to ask for a rescheduling without giving the reason, or mentioning personal reasons if probed. Another approach that allows the candidate some flexibility later is to remain as vague as possible with the details, without actually providing any false information.
Sticking to the truth allows facing the rescheduled interview with confidence and providing follow up details if the interviewer decides to pursue the matter as a measure of the candidate’s honesty before making the hiring decision.
