After the interview, write a letter. A real one. On paper. In handwriting. Addressed to the panellists. You can do one addressed to them all or one addressed to each. If you address one to each, make it clear that you have written the same letter to each individually. Say something like “I am writing to each of you following our meeting earlier yesterday.” Get the dates right.
Thank them for the opportunity, thank them for all the information they gave you. Confirm information such as hours, pay, time off, benefits and so on and then say that you look forward to hearing from them with what you hope will be a favourable response.
If you want to sit around the corner in a café or library and write your letters, do.
Have that delivered at the very latest early the very next morning, even if you have to send it in a Grab or similar. You want it on their desk before they start work.
That single thing acts as a reminder, demonstrates diligence, courtesy, professionalism, business-attitude. And for the vast majority of jobs, you will be the only one that bothers and so, if the letter is done properly, it’s your secret weapon. Everyone needs a card up their sleeve, a little trick, a differentiating factor. Everything you do has the potential to be that differentiating factor. A hand-written thank you note adds something special.
