"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

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.

    Customer Success Manager Interview

    Anonymous Employee in Chicago, IL
    Accepted Offer
    Positive Experience
    Difficult Interview
    Application

    I applied through an employee referral I interviewed at Slack (Chicago, IL) in Jun 2020

    Interview

    The interview process was thorough and very transparent. It started with a phone screen with a recruiter. It was conversational and didn’t feel uncomfortable at all. My recruiter also recently went through Slack’s interview process/virtual onboarding so I found it helpful to hear about her personal experience firsthand and it got me really excited about the opportunity. Next was a pretty intense chronological interview with two managers, including the hiring manager. This interview was about 90 minutes long and not only consisted of walking through my professional resume but also drilling into specifics such as why I selected my college and what each manager I’ve ever had would say about me! This felt like the most critical part of the interview process and luckily, I felt thoroughly prepped by my recruiter(s) beforehand. They let me know pretty quickly that I made it to the final round (a presentation) and were accommodating with giving me the time I needed to prep. The final interview was a multi-prompt presentation to three managers. Again, my recruiter met with me in advance to thoroughly review expectations, provide advice, and answer questions. All very helpful. The various presentation prompts felt like they were trying to gauge a number of different things — overall presentation style with customers, ability to answer questions on the fly, concrete examples of your success/personal process, and cultural fit. I was a little tight on time and did not get to ask many questions to the three managers at the end but luckily I was extended an offer shortly after. I was interviewing during the pandemic so I truly appreciated that my recruiter provided proactive updates every step of the way. She made the experience less stressful and very pleasant!
