Which method is generally considered less effective for sending thank-you communications after a panel interview?
Sending a single mass email to all participants.
Personalization is key in the post-interview follow-up, mirroring the attention paid during the interview itself. Sending a generic, mass email to everyone who interviewed you is significantly less effective because it fails to demonstrate that you absorbed the specific contributions of each person. The ideal protocol requires sending individualized thank-you notes to every single panelist, provided contact information is available, ensuring each note references a unique moment, piece of advice, or specific concern that individual raised, thereby confirming active listening to everyone present.
