Pros

Comprehensive, well planned onboarding process with a mentorship program, regular feedback and peer support. Unbelievable perks and a strong emphasis on "work hard, then go home" (you'll hear it a lot). Weekly boosts in morale and engagement with catered lunches, hot chocolate bars, happy hours and board game hours. Really great place to work.

Cons

Very steep learning curve, though it's well terraced and constructive. Most new hires comment on "imposter syndrome", though it's pretty standard and dissolves quickly.

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.
