Avantages
Opportunities for career growth exist and hard work is rewarded There are some good people working here that are trying to make a positive difference. Unfortunately they are outnumbered by people who aren't helping the situation.
Inconvénients
Large organisations that "feel like a startup", are "fast paced" and where "no two days are the same" are red flags (in this case) for poor management and inter-departmental dysfunction. There are some companies that can strike the right balance between feeling like a startup and being a large enterprise, but this wasn't one of them. They are in desperate need of an influx of new staff who have experience in scaling out a company that has experienced 10x growth. Dexcom feels more like a collection of organisations with a shared goal, rather than a single employer, with each of these organisations prioritising different things, with incongruent methods and who all need you to work on something else, at the same time. A lot of this comes down to improper structuring of teams and a culture of role ambiguity throughout the company. There are high levels of stress and it is very easy to end up with an unmanageable workload. Deadlines are tight and frequent, context switching is a daily if not hourly occurrence and unpaid overtime can become a habit rather than the exception. I would think twice before applying to work here, people get burned out.
