Intact interview questions

I got an opportunity to interview for intact via referral. It seemed good when I received the call for interview. But the interview only got scheduled after 2 reminders to the HR. The hiring manager and Agile coach took the interview. Hiring manager had list of questions to ask, but I felt she was exhausted with the work but Agile coach hardly had 1-2 question to ask and seemed to be not interested. I still gave my interview well and energetically. 1 week passed by, 2 weeks passed by, well now it's a month. No response from the HR good or bad. I followed thrice about the interview results , yet no results or reply. This is the first time I have ever experienced that HR didn't respond with any results nor replied to my follow up. It's a negative interview experience I had for intact.
