PUMA Finance interview questions

Had a phone call with HR then got called in for an in person interview. That seemed to go well, although the hiring manager seemed somewhat distracted during our conversation. After the interview, I reached out to HR to get contact info for the people I met with to email them thank you’s and I never got a response. Tried following up twice more over the next couple of weeks and silence. They emphasized to reach out anytime with questions and now it’s been about a month and haven’t even gotten a response to my original request, let alone anything else. I read other reviews warning of this kind of behavior but to my fault, I didn’t listen. A company with this big of a name to be this rude and unprofessional... is giving them a bad image. If this is how they treat their candidates, how do they treat their employees? A simple one sentence answer that they went with someone else or they haven’t made a decision, anything would be better than blatantly ignoring people. Still waiting...
