Pros

Slack has a beautiful office in SF which is one of the most wonderful offices I have worked at Aesthetically. Good Co-workers who are nice and work together collaboratively

Cons

Everything else especially Management. The Management is very traditional, and has low diversity although Slack stresses on being a very diverse culture and tries to portray this via Social Media or Articles however internally that's not very true. There are no Managers who I can relate to who, like other Unicorn startups are less traditional, new generation, energetic and diverse. I also wish we had a more Front End specific Managers because most Managers here are not very good at Front End Engineering which causes discussion gaps between Engineers and Managers.

Pros

From the moment that I started the recruitment/interview process Alan and the team were clear, open, honest and professional. It is hands down the best hiring experience that I have ever had in my career. The on-boarding was thorough, really well structured and organized and because we are using Slack day to day to communicate and work i feel really clear to what I should be learning without the distraction of 100's of emails , i feel that i am getting up to speed quicker than any other company i've worked for and not felt overwhelmed. Lastly the team and the environment are fabulous, people seem to join and stay and i love that, makes me excited to be a part of the Slack journey :)

Cons

At the moment I cannot honestly think of anything
