- 5.0Nov 10, 2023Sofware Engineer InternFormer Employee, less than 1 yearSan Fernando, CA
Pros
Great company culture Good benefits
Cons
Did not encounter any cons while working there
- 3.0Nov 6, 2023Senior Software EngineerFormer Employee, more than 1 year
Pros
Excellent compensation, interesting tech, they employ some incredibly smart people, remote-first and highly flexible
Cons
There are constant team and org reorganizations, the quality organization has been eliminated while the scope of the application is exploding, and there is no recourse for poor management as feedback flows one direction only, per Salesforce design.
1 - 2.0Nov 6, 2023Anonymous EmployeeCurrent Employee, more than 3 years
Pros
I'm fully remote and when I turn the laptop off, I don't have to think about how awful this place is or how mediocre my colleagues are.
Cons
The leadership is vapid, the strategy is nonexistent, and the product is festering. Since the Salesforce acquisition, there is no innovation.
2 - 4.0Nov 7, 2023Senior Account ExecutiveCurrent EmployeeSan Francisco, CA
Pros
Great team, holding on to the culture before the acquisition, solid product roadmap.
Cons
Salesforce acquisition has muddied the waters a lot, constant fear of layoffs, constant org changes.
- 4.0Nov 10, 2023Product DesignerCurrent Employee, more than 3 yearsNew York, NY
Pros
Good work-life balance, interesting to work on, people are smart and kind, design is valued
Cons
Salesforce corporate stuff, company direction is confusing since Stewart left
- 3.0Aug 21, 2023Sr. Mid Market Account ExecutiveCurrent Employee, more than 1 yearIrvine, CA
Pros
Slack's product and culture (outside of Salesforce influence) is second-to-none. The positive reception and enthusiasm end-users have for the product is super encouraging to see as an employee. After the Salesforce acquisition and Co-Founder/CEO Stewart Butterfield's departure, new CEO Lidiane Jones took the reigns, and she has exceeded my expectations for Stewart's replacement. She recognizes the unique value Slack & its culture brings to the table and seems to work to protect it.
Cons
Upon full integration post-acquisition by Salesforce, automated processes and tools that employees were accustomed to (and built as a result of our value prop/company outlook of automating any processes possible to increase efficiency and productivity) were replaced by old, antiquated tools and processes. I can no longer to the job I used to do. There's a lot of attrition and morale is low; leadership is also being replaced by old-guard Salesforce leaders.
4 - 4.0Aug 9, 2023Staff Software EngineerFormer Employee, more than 3 yearsSan Francisco, CA
Pros
Slack is a great product. It was fun to work on the product. They offer unlimited PTOs. Also full-remote positions are available.
Cons
Slack is not a tech company but a product company. Most of the middle managers are non-technical. This causes low quality decisions in system architecture, hiring, and promotions. They don't know what they are doing.

Management and a “employees ego” are toxic.

Salesforce culture and layoffs causing negative morale
- 4.0Oct 16, 2023Enterprise Account ExecutiveCurrent Employee, more than 1 yearSan Francisco, CA
Pros
Smart people, great product, encouraging environment
Cons
Lack of innovation, not a "need to have" if using other tools
