Post interview etiquette can be a tricky one - should you contact the interviewer to tell them something that you realised you forgot to talk about, or do you risk coming across desperate? Is it worth sending them an email to thank them for their time, or could that appear pushy?
It's important to remember that most interviewers do not and cannot make the decision immediately. As long as the interview went well then a friendly email thanking them for a great meeting (it's worth using a different word to interview depending on company culture) with no pressure of wanting to know the outcome can help to remind them of you.
If you're looking for a reason to follow up with your interviewer, you might consider sending them something you referred to in the interview, such as an interesting blog post, a fact or something referring to how you could be successful in the role.
In fact, the process of interviewing and following up afterwards is not too dissimilar to dating - in the sense that you'll want to find a reason to follow up so that you are at the forefront of the interviewer's mind and get chosen for the role.
If you’re told that a hiring decision is going to be made within 24 hours there may be no need to reinforce a good interview, but a friendly email does no harm – ideally one that throws in one small but important piece of evidence. If the process is more extended, maintain your visibility by getting in touch, even if it’s just to say thank you.
