So I had my first real job interview today at the local hospital. Actually, during the 2 hours I was there, I talked to 4 people overall. I plan on sending thank yous to them all but I’m not exactly sure what I’m supposed to tell them in order for these to be real kiss-ass emails. What are you tactics for thank you emails/letters after an interview?
I send emails rather than letters. Some people send them immediately - the next day - but I tend to wait a few days to remind the people that I exist. I figure if I send it immediately, they’ll see it immediately, then immediately forget me. 
I try to touch on a point that was unique to the conversation I had with that individual, and that emphasizes some quality that I have that is important to success in the position.
Good luck.
I’ve never sent one. I thank the people who hire me, not the ones who don’t. Interviewers aren’t doing you a favor by interviewing you.
My personal feeling is, if you haven’t impressed them enough in the interview to be hired, you won’t be regardless of any post-interview action. If you have impressed them enough, they will hire you whether you send a card or not.
I presently work at a hospital. I’ve participated in two other hires since I started. Whether someone thanked us for an interview or not was not a factor at all, never even mentioned.
I agree that a thank you probably won’t make a difference, but it can’t hurt. A very short email would be good. You can also invite them to call or email you if they have anything else to ask. They won’t, but it will get your name, number, and email address in their inbox.
I also agree that it is good to wait two or three days - no longer, though.
On the other hand, this is an excellent chance to fix any mistakes you have made during the interview. An interview is a chance to sell yourself, and this is a second chance, and you won’t take it?
No, send it within 24 hours, so that the interviewers still has a fresh memory of you, of who you are and what you said. Reinforce the positive image of you by the thank you letter, so you stand out among all the candidates.
