When you have an appointment for a job interview and you can’t make it, what should you do? The answer depends on whether you have decided you don’t want the job and want to cancel completely or if you want to reschedule for another date and time.
How to Cancel a Job Interview
In either case, it’s important to let the employer know as soon as possible that you’re not going to make it. Don’t wait until the last minute.
The interviewer’s time is valuable, and another applicant can be scheduled in the time slot you’re giving up. You also want to stay on good terms with the employer in case you want to reschedule or if another job opens up that’s a better fit.
