      Best place I've worked at

      Anonymous employee
      Recommend
      CEO approval
      Business Outlook

      Pros

      - The culture at Slack is very inclusive. I've had imposter syndrome everywhere else I've worked. This is the first place that gives me a sense of belonging - Leadership trusts you with important work, and lets you drive it to completion. I've been doing the best work of my career here so far

      Cons

      - Since its a growing company, there is a lot of work to be done. This gets overwhelming at times, but is completely rewarding.

      Best Company I've Ever Worked For

      Business Outlook

      Pros

      Overall, Slack is a wonderful place to work, to be an engineer, or to be an engineering manager. I've been lucky enough to be both an IC and an EM at Slack, and over the past two years I've worked with incredible colleagues. We're shipping a well loved product that's fun to use, and we're able to ship it without working crazy hours. Work life balance is great, and so are benefits. During the pandemic they've been giving everyone in the company 1 extra day off a month and it's just been wonderful.

      Cons

      If you don't have a manager invested in helping you grow your career, it's going to be a challenge to do it. The engineering promotion process is very manager driven, including packets written by the manager. If you don't have the proper support, it's tough to get promotions or switch from IC to EM. If you do, it's a great place to grow your career. On a day to day basis, there are still a number of things that cause engineers on my team pain in the codebase. Flaky tests are probably culprit number one. Code health has improved a lot in the past year, but there's still a ways to go.
