Pros
1. Great Team: Very impressive amount of talent at the company in all roles. I'm continually impressed by how smart and capable my coworkers are. 2. Immediate Responsibility: From day one you are doing impactful work that is likely to be implemented in the live products on a very short timescale. 3. Exciting Market-Space: This is a new and emerging market, and C3 are looking like being one of the leaders paving the way in the field. Lots of opportunity for growth as a company.
Cons
1. Occasional Long Hours: As goes hand in hand with working on difficult, complex problems and operating on a start up time scale it is sometimes necessary to work nights or weekends. 2. Intimidating CEO: While I have a lot of faith in the CEO from a business and vision perspective it's become clear that a lot of people in the office seem very intimidated by him, bordering on being afraid of him. Not a real issue for me as my interactions are limited, but doesn't seem great for company culture.
