I recently received an offer from Bain that I have decided to accept. I have communicated this already through the proper channels and sent off my contract. I have also emailed my 1st round interviewers who were already in touch with me (essentially to encourage me to accept the offer). Until now, I've had no email exchange with the partners that interviewed me in the final round. Is it appropriate for me to send them a thank you email and to inform them myself that I have accepted to offer? Thanks.
