Dexcom interview questions

Normal interview process- I applied online and was contacted by a human resources rep and did a first interview with her. A couple days later I did another interview with an area supervisor. Both people were very nice and professional. I was told I'd hear back soon, but was completely ghosted after that. After 4 days, I emailed the HR rep for an update, and she never responded. A week after that, I emailed again. Nothing. I was pretty disappointed in the lack of communication once they decided I wasn't a good fit.
