Pros

People! The team at Slack is amazing to work with! People are not only extremely smart and competent bu are also very welcoming and empathetic to one another. Fun product to develop! The product has a huge impact on people's working life and it is cool to develop. Every idea counts, even if you are a junior developer! Great work/life balance! Everyone is very aware of each other time and are concerned about people having time relax and take care of themselves. Work hours are very flexible.

Cons

Most employees are in the US, so sometimes, in the all hands and town halls the information shared applies more the them than to the rest of the company, which can cause a bit of confusion.

Pros

Very generous compensation and benefits. Staff are valued and trusted, our wellbeing is always a top priority. This means flexible working hours, time off when needed, access to resources and benefits to take care of physical and mental health, lots of internal opportunities for further development and learning.

Cons

I'm trying to be super critical but honestly for me I couldn't ask for any more. We are constantly in a state of hyper-growth which means it can be fast paced and pretty demanding work. If we did not have such investment in our wellbeing it could be easy to burn out. It's important to disconnect and thankfully we are encouraged to do so.

Pros

There's so much that I can write about how much I've enjoyed my time at Slack, but if I had to sum it up, it comes down to the power of the platform that we sell, and the brilliance of the people that I get to work with on a day-to-day basis. Culturally, you can't beat the employee experience. Our office is so close, regardless of the department you work in. From a career perspective, there's tons of opportunity. In my experience, our leadership team has always prioritized career growth, and I couldn't be more appreciative.

Cons

I really can't think of any. I only have the most incredible things to say.
