I was wondering if anyone could please provide any insight on how I can go about thanking people I've networked with and who have helped me along the way after I get an offer and accept. (I've read many networking posts here, but most seem to focus on the before the offer part.) These are people I've had phone calls with, and emailed them about updates along my recruiting process. I really want to keep in contact with these people, but am not sure how.
Obviously, I will shoot out thank you emails. For the analysts/associates, I was thinking of asking them out to grab coffee? But what is the appropriate way to thank an ED/MD? Is an email enough? Can I ask for a phone call a few months down the line just to catch up and learn more about the job?
Thanks everyone in advance!
Edit: Sorry, just wanted to clarify my situation. I got the offer, accepted the offer, and have about 4 ED's to thank because they actually pulled for me. I really want to send handwritten notes, but only have their building address and don't know how mail works.
