Pros

Overall challenging but rewarding, fun conversations with doctors due to product differentiation. Many brilliant minds working towards a common goal.

Cons

Being a startup creates some challenges over the years but the company reacts quickly and seems to anticipate needed changes with fast growth.

Pros

Ok. I’ve been in the company for less than 6 months and I’m enjoying it so far. The benefits are good (not paying anything on my insurance because I have Kaiser). People makes the culture and I really love the people who works here. There are free snacks and lunch and I heard the property management company is opening a gym somewhere nearby. I don’t really have any complaints so I don’t really understand why we have CLS complaining about the company when they are making over 120k a year plus all these benefits. I don’t understand why they are complaining when they all have these flexibility working in the lab while using their phones and chit-chatting at the same time. Honestly, if I hate the company, I’ll leave. I mean all they have is a license anyways. They should leave and let more deserving people who actually does the job and not act like a priviliged person who wanted to be hand-spooned. It is terrible.

Cons

No complaints so far but maybe more team building events.
