HR was so unprofessional. She scheduled a time for a phone screening interview but didn't call until after 15 minutes. When she finally called, I answered but didn't hear anything from her, and then she hung up. I tried calling back several times, but all my calls went to voicemail. If you don't want to work, please do not waste people's time. It's so unprofessional and rude of you. I never experience such thing from any HR before.
