Pros

Work with some of the brightest and diverse people in tech. A lot of the engineers at Slack were previously at Facebook, Google, etc. and helped build out those companies. Awesome perks, good, food, great snacks, amazing founders very transparent work place. The people at Slack are very emphatic and help you when you need it. Oh yeah, free weekly massages are pretty awesome.

Cons

Tough deadlines can be stressful at times. Slack doesn't have catered food all days of the week (Maybe in the future :thinkingFace:). Some teams definitely have more work to do than others. If you're an engineer on one of these teams life can be a little stressful.

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.
