Want an easy way to stand out from other job applicants? It may sound 'old school,' but send a thank you note after your interview.
I get so few: believe me, I notice each one.
In addition to satisying any questions of etiquette, you can use a thank you note to reinforce key points from your interview--or to introduce brilliant answers that escaped you in the pressure of the moment.
With a thank you note, you check in and you also communicate continued interest. And it's one more opportunity to market your gifts and potential contributions.
It doesn't have to be long; doesn't have to be fancy. Three or five sentences by e-mail should suffice. It's quick, much easier than your cover letter, and a lot of bang for the buck.
