Pros

I've been with Slack over a month and it's clear this company is led by an extraordinary CEO! A CEO who cares as much about people as he does the bottom line. His thought process trickles down throughout the leadership team and managers making Slack truly a wonderful place to work! Slack the product is an amazing product! While I used Slack at my previous employer, it wasn't near to the extent I'm now getting to use it. It's a product that truly makes work life simpler, while also adding in fun with all the emoji uses! Slack benefits are phenomenal! They have 3 health options in CA and that are 100% paid for by Slack for the employee AND the employee's dependents. This is a HUGE annual savings. They offer 20 paid vacation days, 10 paid sick days, 2 paid volunteer days, paid Company Shut Down days between Christmas and New Years and paid Holidays. They offer a cell phone and wellness stipend which are automatically added into your paychecks. Plus up to $1000 reimbursement to set up a home office and up to $2000 reimbursement for professional growth! Slack's pay is generous! They offer generous base salaries, annual bonuses and stock! A portion of your stock starts vesting at 12 months! Career opportunities also seem to be abundant at Slack. While Slack has over 2300+ remote employees (currently due to COVID), they have really mastered the "remote" workforce culture by having employees feel engaged without micro-management. I've feel blessed to have landed at Slack!

Cons

I have not come across a single "con".

Pros

Fast-paced company on a rapid growth trajectory and evolving product. Incredible culture that is collaborative and supports employees on a human level.

Cons

Continue to develop employees in more junior regions. It can feel like the central region is behind the East and West.

Warm, inclusive, playful engineering culture (that still ships great software)

Pros

The engineering culture at Slack makes special efforts to be warm and inclusive and sane. In particular, "work hand and go home"... or during covid, "work hard then stop working." We encourage working sustainable hours, except for when absolutely necessary. The massive social workspace with amazing active channels (#dogs, #trash-pandas, #cooking, #baking, #sf-classifieds) provides a way to make real connections with people in the company who you might not otherwise interact with. We ship software that people want to pay for!

Cons

So. Many. Channels. It can be exhausting to figure out which channels to actually pay attention to, and how to keep up with channels while also getting work done. Using hack is challenging because there are hardly any public resources or tools for it.
