A
thank-you email is generally a good professional follow-up after an interview. The message doesn't need to be long. Thank the interviewer, mention something specific from the discussion, reaffirm your interest in the position, and close professionally.

Sending a personalized note within 24 hours is a commonly recommended approach.
