Workiva Solutions Consultant - Technical interview questions

Applied and received confirmation for HR screening fairly quickly. I was booked in for the next stage of the interview process with the Hiring Manager straightaway. This went well, had a thorough discussion about the role, what to expect, my experience, some competency based questions etc. I stayed professional after the interview, sent a thank you email after the interview and chased up for feedback every single week for 4 weeks after the interview. However, Its been now 6 weeks and I am still yet to receive any feedback on how the interview went. I almost feel like I am begging for feedback. Emails, calls have been ignored with no response.
