Savvas Learning Company Principal Software Engineer interview questions

Two rounds. first round is technical, second round with hiring manager, both technical and behavioral questions. After the final round, they just ghosted me. I waited for 2 weeks and asked the recruiter, she said she will ask the hiring manager and get back to me. Nothing came back for another week. Not sure why more and more companies think ghosting people is a good thing to do. It's just terrible and so unprofessional
