Thank you for taking the time to share your experience, and I want to sincerely apologize.
You went through four rounds of interviews and deserved a proper close-out regardless of the outcome. We dropped the ball on communication here, and that's on us. Closing out every candidate is something we take seriously, and we fell short of that standard.
We appreciate the feedback and are using it to do better. Thank you again, and we are truly sorry about this experience.
