An awesome culture! Smart engineers!

Pros

Great benefits (commute, health, etc.). Great culture and values. Helpful coworkers, embodying the company's values to help each other strive and produce the best quality work for customers. The company is the first advocate for employees' well-being (work-life balance). Oh ... and most importantly, a very diverse place (constantly aiming for better).

Cons

If you, unlike me, like a "nerdy" environment with less communication and exchange with coworkers, THIS IS NOT A PLACE FOR YOU.

Pros

People, compensation, product, leadership, engineering processes — all top notch.

Cons

Anything related to Salesforce — HR, layoffs, IT, budgets offices — is poorly managed. It’s a major drag to work for a extremely high functioning company that is owned and controlled by a very poorly functioning company. Also, Marc Benioff is a dork. Imagine a liberal with Trump’s personality.

Horrible data organization

Pros

Perks are great. Building is beautiful. Slack, as a product, is useful.

Cons

Data org has no strategy or vision. Most engineering managers don't care about their team members. The very few who do aren't supported by the senior leadership. No focus on engineering quality and the happiness of the engineers. VPs and directors overpromise to the execs. They get upset when their unreasonable demands aren't met. Horrendous amount of cross department politics. Constant on-call issues and pages. Small teams supporting large number of projects and constantly struggling to keep up. No appreciation or recognition of th good work. CTO belittles the data org when things go wrong. He seems unhappy with the team, but does nothing to understand and correct any issues. I can keep going but hopefully you got the idea!
