Overall unpleasant experience.
Initially, recruiter was prompt and highly responsive. I was quickly scheduled to interview with hiring manager in what I presume was a screening step. Interview occurred without incident. At conclusion I was told they would get back to me the following week. 1 week passes. No update. I inquire. Days pass, no response. Similar to what I am seeing here on Glassdoor, they are uncommunicative, fail to respond to follow-ups, and thus by definition may be labeled as "ghosters". Just really Bad Form. Frankly, I expected better from Dexcom.
