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

- Intelligent, kind, fun, caring coworkers - Personal/Professional Development Budget for each employee - We take our values to heart and that comes from the top down - The work/life balance is great (work hard and go home) - There is constant discussion among all employees about how we 'do that right thing'. That looks different for everyone, but I appreciate that there is always an open dialogue around the decisions we make across the whole company - Experience managers/leadership. This isn't their first rodeo. - Diversity matters here and is openly discussed - I am able to focus on my work and I know that Slack will do right by me (comp, benefits, culture, work/life balance, etc.) - I could go on and on...

Cons

- If Stewart told me to jump off a cliff, I'd probably do it. - I'd OF COURSE rather be overly PC then not at all...but it can be a bit much sometimes.
