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.
Kontras
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).
