Healthcare Bluebook interview questions

I had a call with someone from HR to discuss a Data Engineer I role. After some discussion, we learned I would be better suited for the Data Engineer II role. She offered to set up a call with the hiring manager for the Level II role instead and I happily accepted. Everything was wonderful until the call ended and I never heard back from anyone again. I reached out at least four times since then for an update, but have been ignored this entire time. I've changed my mind about them as I feel they are extremely rude and unprofessional.

Healthcare Bluebook has a 4 step interview process which includes rounds with HR, hiring manager, and team members. First round was simple and was more focused on personality. Following rounds focused more on technical skills, how you handle situations, and discussion of past experiences and projects.
