I had a phone screen and then was invited to the onsite. It was a bit chaotic as they couldn't figure out who exactly will be interviewing me. But that was okay, I ended being interviewed by about five different people. Standard interview process with some behavioral questions, some technical questions and questions about my experiences. After the interview I received no updates. I followed up with the hiring manager but he just ignored me. I would've understand if they just told me I wasn't a good cultural fit or they found someone better, but apparently they think completely ghosting an applicant is acceptable. Very unprofessional to have me spend an entire afternoon interviewing with them and not even bother telling me a "no". Maybe the hiring manager got fired or something.
