Pros

- Supportive management - Transparency from top of leadership funnel down to individual contributors - Feel like I'm given every tool imaginable to succeed - Culture is welcoming, warm, and incredibly receptive to how COVID is impacting it's workers lives - ORGANIZED -- coming from a very disorganized company prior to joining Slack, the level of almost over-organization is a breath of fresh air

Cons

- Everything has a formulated process, which can be annoying at times when you're trying to close business quickly. But there is obviously a reason for that. - The culture is very much search first and ask questions second, which is by no means the con, however often times we are given so much information spread across so many different channels it's often hard to remember where you heard something.

Pros

Slack has shifted to remote work well and has really supported its employees (financially and emotionally) during these trying times. The high caliber and character of everyone you work with is apparent in almost all interactions.

Cons

Org structures create duplicative work and make roles and responsibilities unclear and create more difficult handoffs across projects.

Pros

I joined Slack after COVID-19 quarantine had already started, so my entire interview process, onboarding, and beyond has taken place remotely. While every company faces challenges due to this situation, I think Slack has handled it exceptionally well. I have felt very supported by the company and my peers in getting set up remotely, and I'm impressed by how quickly the entire company has adapted to working from home and continues to iterate on ways to make this work even better. As someone who used to have a long commute to the office every day, I appreciate that Slack is now allowing employees to work fully remotely in the future. In terms of the work, I feel that I've quickly ramped up on my team's work and have started making impactful contributions soon after joining. It feels like there's a lot of opportunity to take on responsibility and make meaningful contributions, while also being supported in prioritizing your own personal life and health.

Cons

I've struggled a lot with legacy code and learning PHP/Hack, which I didn't know prior to joining and have found difficult to work with. This can be frustrating for engineers who are used to working in more common languages which have more available resources online. The codebase also has some poorly documented / poorly tested areas which are difficult to understand and make changes to (these is mostly legacy code, as standards seem to have increased over time).
