Pros

Slack has an incredible culture and leadership that is unlike anything I've seen at any other company. Everyone lives their values of being empathetic and they really care about their people. The product is amazing and the alignment between different teams is a breath of fresh air.

Cons

Like any fast growing organization, the need to adapt to change is prevalent.

Pros

It's very much a non-corporate company. It's the first company I've been in where every bit of information is made available, no IT secrets here. The people are great, I haven't met a bad apple yet, so far so good.

Cons

There's not as much structure to your work day, which I don't mind but I know plenty of people that would struggle with that.

Pros

There's a very friendly and open atmosphere here. Slack was quick to recognise some of the challenges that reared onboarding remotely and changes were made to combat those. I feel very lucky to work at Slack and feel like I belong here. Our customer-facing approach makes working life easier. They are very transparent and listen to their employees. They hire sound people as well who are there to support you in the long run.

Cons

It can feel like you're forgotten about once onboarding has completed and there are times where I find myself drowning for support because Slack moves at such a fast pace. The way feedback is delivered can sometimes be very harsh and cold without any constructive advice attached.
