Columbia University interview questions

I had a phone screen with HR, which was oddly short and non-specific in terms of questions. There was little explanation of the role, and she deferred most questions to the hiring manager if I proceeded. I then had a great, promising Zoom interview with the hiring manager a few days later. Typical interview questions. Sent a thank you and received a response, which is always nice. Then was completely ghosted. Followed up with HR about a status update and received no response. I understand people are busy, but it's completely unnecessary in today's day and age when messages can be automated to fail to provide a final response noting the role was filled.

1 phone interview, 1 in person group and final one with senior management. Group meeting was with various potential team members. All asking questions around your position and how you would support them.
