Pros

Game changing technology and massive market opportunity ahead - We're 1% penetrated in a 700 million knowledge worker market. Unique culture that emphasizes customer and team first. Great opportunity for career growth: A colleague was promoted to manager role and many others have been promoted into Senior AE roles. Achieved some great milestones in 2017 including landing Large Enterprise logos that few 4 year old companies can boast about: IBM, Oracle, SAP, American Express, Capital One, eBay, Paypal, Walmart. Best parts about working at Slack: Being surround by intelligent, empathetic teammates, helping effect a fundamental change in how people use technology to get work done, exciting personal career growth and earnings opportunities, and visionary leadership from Stewart Butterfield who has surrounded himself with an impressive executive team.

Cons

The sales organization still comprises a smaller percentage of the total employees, so developing a strong voice/seat at the table with larger product and engineering organization has taken time. I've seen positive changes over the last year here so I anticipate progress will continue to improve.

Pros

- Lots of great, smart, hard working people at Slack. - Work on a product enterprise software users enjoy. - Competitive compensation plans.

Cons

- Very bad behaviour at the executive level (including CEO verbally assaulting employees in public Slack channels). - Highly political environment. The highest I've seen in Silicon Valley. (But people don't talk about it out of fear.) - No upward mobility (see highly political environment). - HR is there to protect executives/founders, not employees (but that's common). - High turnover in eng/product/design due to toxic work environment (so you will spend a lot of time interviewing to add to your team)
