I was asked to prepare a sample lecture which took me a lot of time and effort to complete. I then had about 3 different online interviews that lasted the majority of the day. I was given a date for a potential second interview and was told I would be contacted to iron out the details. Ultimately, I was ghosted, never hearing back from anyone. That felt pretty disrespectful and unprofessional, especially in light of the time I spent preparing and engaging in the interview process.
