First, they send an automated email where you select a day/time to interview with a person. No contact info provided, basically we will contact you, don’t contact us feel.
Quick 30 min phone interview with an HR person to screen my qualifications. She wanted me to talk with the hiring manager and move forward quickly, they wanted to fill the role and felt I was a good fit. A week later I had not heard back from anyone. I wanted to follow up to see if there was a change or something, but there is no contact information to reach anyone. After a month I assumed they had a change of heart? Still not sure after several months of not hearing back.
Have some mutual respect to contact your candidates if you decide not to move forward or filled the role. Especially if you have told them you want to move them to the next step of the interview process
