HR was very unhelpful. HR, make yourselves useful to the company by giving candidates who spent their time interviewing at your company feedback after interview. If the Hiring Manager has not reached out to HR with feedback, HR should should reach out to the Hiring Manager and ask for feedback especially in situations when a candidate asks for feedback months after interviewing. No everyone is desperate for a job and wait for ever for feedback and get fooled into another round of interview without feedback for the first round. I accepted another offer and moved on.
