How long should a successful interview last?
As a general rule, a routine face-to-face interview should last around 45 minutes to an hour. A 30-minute interview dialogue is also a decent amount of time. If the interview is 15 minutes or less, this might mean that you won't be contacted for a second one, or get the job for that matter.
Is a 20 minute interview good?
Is having a 20 minute interview a bad sign? In most cases, with good interviews generally running 45 minutes to one and a half hours, a 20 minute interview is a bad sign. That's barely enough time for the interviewer to get to know a candidate, especially if it's not an entry level position.
Do interviews really last an hour?
In-person interviews typically last between 45 minutes and an hour and a half, depending on the hiring manager and if you need to meet with multiple employees. In some cases, you may interview with a company for up to a full day, performing some of the primary job duties under supervision.
