Medtronic Quality Engineer Summer interview questions

Applied online in January and got an email 2 months later asking to set up a phone interview with HR. It was easy behavioral questions and nailed a second interview with managers who were interested in hiring me. I got unlucky and got interviewed by group of engineers with thick accents. They told me that I would get a phone call whether I got the position or not. Waited a few weeks then I called and emailed them and did not get any response back. I ended up emailing HR and she told me all the positions were filled.
