I was contacted by a senior manager within the organization who set up the interview. I was interviewed by 3 senior managers including the buildings lead (4 total). The interview questions were typical for a senior level position with significant focus on managerial and soft skills. After the interview I followed up with emails and written thank you cards. Two of the members of the panel responded and thanked me for the emails and cards. I was ignored by the hiring manager. Eventually, I didn't hear back from anyone. No offer was made, no follow up to say I didn't get the job, and no debrief on how I could do better. I was basically ghosted.
