There are a few pieces of interview advice that are burned into my brain better than any Britney Spears song, which is really saying something. They go a little something like this: bring a printed resume, ask questions at the end and, maybe the most contended, send a thank you note after the interview.

While not everyone agrees interviewees need to send a thank-you note (just look at the controversy around this Business Insider article), I think everyone could agree that a lot of people who send them mess them up.

Not by sending them too early or by using the wrong salutation or by forgoing the written letter, three anxieties I have actually Googled.

No. A common way people mess up thank you notes is by sending the same one, over and over, to people who are all getting in a room together to discuss their future employment.

This common mistake can cost you the job
