Pros
I reviewed Slack before the Salesforce acquisition and it was a glowing 5 stars so I'll just repeat what has remained after being a newly minted Salesforce employee for 6 months. - Work-life balance is still amazing - Benefits are great - Very impactful work depending on your project/team - More diverse than most tech companies
Cons
The culture has very much shifted and many engineers like myself feel more like a cog in a machine than ever before since the Salesforce acquisition. I can respect this model works for some as it depends on where you are in your life but as someone who wanted growth and challenge, you really need to make sure you're on the right engineering team at Slack that is doing the visible work. Because I felt like my growth had stagnated and that the bureaucracy of working at a big company was getting to me, I decided it was time to leave after several years of being at Slack. - very high turnover since the acquisition of Salesforce (mostly folks getting higher titles at startups) - dealing with Salesforce culture and bureaucracy (worse at D&I)
