I got completely ghosted 3 interviews deep. After my 3rd interview i never heard from them again, regardless of the countless amount of times I checked in for an update.

Applied online, was contacted for a phone interview. Phone interview was a quick, easy screening. Then set up a virtual interview on Zoom. She rescheduled the interview on short notice. Interview was difficult. Was then asked to provide examples of work. Finally heard back after several months. I found it incredibly rude to ignore emails especially after initial interest with several interviews and to provide examples of work. Overall, very unprofessional.
