Scripps Health Lab Assistant interview questions

I had a brief phone interview with HR and was offered an in-person interview for the following week. Both interviewers were friendly and I thought the interview went really well. They most had standard questions like, how do you handle working with a coworker you don't get along with or with a difficult patient. After 2 weeks of not hearing back, I tried contacting HR multiple times for an update but never heard back. They just left me hanging. Very unprofessional.
