    I have been working at GreatHorn full-time


    The people. This is the smartest group of people I have worked with in my career, and all of them are people I would hang out with outside of work. It is by far the most human environment I have worked in since I left teaching, and there is a company-wide commitment to putting our lives ahead of our work. No question that hard work is expected, and extra hours when necessary, but family and quality of life are valued and balanced against business needs.


    None, in my opinion. I like working hard with a dedicated and communicative team, and GreatHorn delivers.

    Advice to Management

    Keep doing what you're doing.

    QA Lead Interview

    Anonymous Employee in Belmont, MA
    Accepted Offer
    Positive Experience
    Easy Interview


    I applied online. The process took 1 day. I interviewed at GreatHorn (Belmont, MA) in December 2017.


    The hiring manager contacted me and set up a phone screen. I spoke with the lead software engineer. We discussed the role and how it would support the team's mission. The phone screen was focused and the discussion concentrated on the role of Software QA in a startup environment and small teams. For the onsite, I met the Lead Software Engineer, DevOps, Product management and the CTO. The team is high performing and a big factor is how you'll interact with the team and if you're a fit for the company. Overall the experience was great, especially compared to the bloated process you find with larger companies. The phone screen was set up shortly after I applied and I had an offer from the CTO a few hours after my onsite interview concluded. The entire process was professional and the interviewers friendly and courteous.
