THE BEST WAYS TO REQUEST OFF WORK FOR AN INTERVIEW
Honesty is always the best policy. That said, we do not recommend telling your employer you need time off to interview with another company (for obvious reasons). We'd ask in person or call and request the time off (such as: can I leave a couple of hours early on Friday). If approved, send a reminder email confirming your time off and mention in the email that you'll try to arrive a couple of hours early to make up the time.
Also, if the initial interview times need to be changed, please provide alternative days and times that would be better for your interview.
