Cool product but not cool place to work

Pros

-Brand name -The product is cool -Hot startup -The work you do here is highly visible -People here are very friendly -Delicious Monday lunch (only 1 day provided lunch here, but we also get provided Friday breakfast) -Cool CEO

Cons

-Fakeness in culture is starting to show. There is no explicit rule that you have to use emoji in messages or smile all the time, but your colleagues will judge you negatively if you don't. If you're having a bad day, be sure to add those emoji in your messages and fake a smile so no one knows you're human. -I've seen a lot of code. The code here is by far the worst -Opportunity to learn weird non industry standard practices -Weakest middle management -For a place that creates a product that allows working remotely easier, it's surprisingly frowned upon. They won't say anything, but they will judge you. -You tell your manager something that bothers you/something on your mind and there will be no action. You'll be lucky to hear back. -Compensation is on the lower side. Slack knows that it's Slack and people want to work here because of the hot product. They don't negotiate much because they know you want them more badly than they want you. (guilty)

Pros

- truly some brilliant, fun to work with people - a fantastic look at how a quickly growing company leveraged a dead simple (sometimes painfully so) infra to build a huge business - people outside of the product org are so nice and friendly, it makes the job seem almost fun - some excellent managers around, lots of people you would hope to work with again

Cons

Cons - the larger more interesting opportunities require a very strange and unpredictable amount of pleasing the right people and not rocking the boat - do not disagree even cordially with people have been there long enough, you will be punished - routinely underpay juniors, feel bad for em - too many “technical” managers avoiding what they actually need to be doing...managing!

Cons

The company hierarchical. Management does not listen to or take their employees seriously. Folks draw a circle around their responsibilities to minimize liability. The company smokes their own product, meaning that they are great because they believe they are great. Management is green and has no clue how to deal with friction within the team or how to motivate people. The product has serious issues, but if you bring them up along with possible solutions, you manager will not be happy and tell you that these issues are not our concern because a different team is responsible for the feature in question. There is no sense of urgency. The company is very successful, but resting on your laurels is an invitation to competitors to eat your lunch. The product does not scale well on the server-side. The word "proactive" is not in anybody's dictionary. We're all waiting for fires to fight. Teams are poorly organized. Instead of forming small two or three person teams to implement a feature, some people are assigned massive tasks while others are given small tasks that have to be stretched out to make an appearance of effort. Some teams can have three or four managers in the span of a single year.
