Streamline Health Sales Development Representative (SDR) interview questions

This company contacted me initially for an interview with the hiring manager after I submitted my application. The hiring manager said they were mostly done with interviewing but saw my resume and wanted to speak with me. Had a pretty good conversation and moved to the next round, which was with another SDR and an AE. Thought the conversation went well. Didn't hear back for awhile and reached out via email to the hiring manager who said they were still interviewing candidates. A couple weeks later sent another email. Never got a response. Unprofessional to say the least.
