Following up after an interview is an essential part of the job search. You are encouraged to send a handwritten note or an email to the people you interviewed with.
It's a very basic task, but very few job seekers actually take the time to do it. There is very little downside aside from the few minutes it takes to write a quick note.
By sending a thank you note, you can make a positive impression one more time and perhaps influence the hiring decision.
