Pros

Fast paced, most engineering work is figuring out how to get bigger. I have a lot of flexibility on what I will work on. Great benefits. I do not work with any jerks.

Cons

Growing pains: cramped space, confused managers. Can be high pressure depending on team. Dogmatically far-left-wing politics.

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.
