    Senior Software Engineer Interview

    Anonymous Interview Candidate in Mississauga, ON
    No Offer
    Negative Experience
    Easy Interview

    Application

    I applied online. The process took 3+ weeks. I interviewed at Slack (Mississauga, ON) in October 2020.

    Interview

    A worst process ever! The recruiting team does not even respond back to the rounds taken with a genuine feedback. They first shortlist the CV but after the interview no one responds appropriately to my emails.

    Did not expect this from such an esteemed organization.

    Please respect the candidates interest and effort put in to attend the interviews.

Company Updates

  • "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

  • "My colleagues are some of the most caring, curious and hard working people I've ever met. There's a constant pursuit to be better humans -- for each other, for ourselves, and for our community. We can all be exactly who we are and uniqueness is encouraged." — Meaghan Riley, Customer Experience Agent, she/her
