      Great place to work - Senior Front End Engineer Slack Employee Review

      Pros

      Supportive engineering culture. Good perks but not over the top and professional. Good work-life balance.

      Cons

      Rapid employee growth means a lot of people are new and few people seem to have in-depth knowledge. Development pace can feel a bit slow coming from a smaller company. Overly-cautious about unit tests and logging, while lacking in integration and system tests to prevent incidents.

      Pros

      Coworkers are smart, kind, and supportive. Good product. Interesting problems to solve.

      Cons

      Culture has lost its way a bit under Salesforce. Tight budget, hiring freezes, and tight ACV goals and deadlines have changed priorities across the company for the worse. Stock isn't doing well.
