Thank you emails after interviews

Do you guys always email the interviewer/recruiter after your interviews? does it actually increase your chances? Or rather, does it look bad if you don’t?

I always do, feel like these days you stick out in a bad a way if you don’t bc so many people do it

I don’t, I just say it during the interview. I think it depends on the industry? Like for instance, I don’t think it matters too much in finance (I’m interviewing for quant jobs).

I never write them…maybe this has been screwing me a bit
