Pros

Wonderful, smart, and humble co-workers; Lots of improvements to make as we scale; Inspirational company that offers above and beyond benefits and culture to prioritize family, mental health, and great work.

Cons

Odd dynamic between recruiting and other parts of the business. Definitely need to optimize to improve the effectiveness of recruiting. Interesting groups of people with various perspectives depending on tenure at Slack.

People First Mentality

Pros

I interviewed during Covid and was concerned about switching organizations during a tough time. The people during the interview process came off sincere and shared the value of people first. I have months in and this is very true.

Cons

Very steep learning curve. If you have not worked in Slack full time, it can be very overwhelming. It is a very different way of working.
