Approves of CEO

I have been working at Slack full-time for more than a year

Pros

Culture encourages people to naturally be themselves, it stopped being classified as work for me a long time ago and more of a place my brain goes to think about people collaborate. Work life

Cons

It is a big responsibility to handle the collaboration of the size of customers we have, it is not necessary a negative but something to remember from time to time.

    Interview

    You can expect:

    1. One or two assignments to understand your communication, and ability to answer technical questions

    2. Take home coding test (relatively basic compared to a traditional software engineering interview)

    3. A somewhat grueling onsite (or these days, a remote Zoom). Expect to be interviewed for around 3 hours straight.
    Interview

    Expect a basic take-home coding assignment to determine your ability to understand the essentials of platform development.

'I wanted to share with you the wonderful opportunity Slack has given me to give back to my community. Five and a half years ago I was forced to flee my home country because of homophobia. When I arrived in the U.S. I hid, working in fast food and fearing a return to my country. Then I won the protection of asylum, the right to stay here thanks to Oasis Legal Services. I could finally embrace my life and return to the work I love, designing software. I found a community of friends, and eventually I found Slack which is extremely welcoming of the LGBTQ+ community.' — Gerson Garcia Pineda, Sr. Software Engineer, Test Automation, he/him
