  • One in four of us have suffered or will suffer from mental ill health at some point in our lifetime, yet many are reluctant to talk about it. At dunnhumby we want to encourage a culture where people feel comfortable to speak out and share how they feel, and to provide practical means of support. Which is why we're very excited to introduce dh Thrive – our employee-led, business-supported movement focussing on the mental health and emotional wellbeing of people at dunnhumby. Launching across our UK & Ireland offices in May, we’re then aiming to build on the initial launch and roll out across our global offices in the future. Read here:

    It's time to talk | Launching dh Thrive

    stig ? ma a mark of disgrace or infamy; a stain or reproach, as on one's reputation. Stigma erodes confidence that mental illnesses are real, treatable heath conditions. Stigma means erecting barriers around effective treatment and recovery. It's time to take those barriers down. It's time to end the stigma.

    Positive Experience
    Average Interview


    I applied through a recruiter. The process took 3 weeks. I interviewed at dunnhumby (Cincinnati, OH).


    If you pass the phone interview,you are invited to get a face to face interview in the company building, You get to meet at least 4 people, including the colleagues you are going to work with and the directors/managers you are going to report. Very friendly people. Prepare to explain all the work you mentioned in your resume. Especially, if you are going to work on an analytic side, you need to be ready for very smart and though questions.

    Interview Questions

    • Technical people will be given a SAS/SQL exam to test their basic programming skills.

      Also, knowing the culture of the company and integrating those values into your answers might help you out!   Answer Question


    There was no negotiation! The offer was already very good!
