    I have been working at GNS Healthcare full-time (Less than a year)


    I am working here as a data scientist with healthcare payer client. The technologies here are competitive (e.g., REFS proprietary algorithm, daily operation on AWS platform, development of state-of-the-art new algorithm using tensorflow). The colleagues here are genius with sophisticated math and computational background; the research/tech leadership here is wonderful within my team (numeric or R&D team) as I can only speak for my team; the projects about patient management collaborated with the payer client is very attractive and exciting to me as it will enable translate the technology into real world value - patient welfare/satisfaction, efficacy of healthcare service and financial cost saving. There are a lot of growth room in GNS for an employee, in new technology, business sense and management role.

    The salary rewards those talents recruited in. I think the salary is quite competitive in Greater Boston area, though becomes weaker as compared to Seattle or Bay Area. They do provide stock options. The benefits, except the downside of no company 401k match, are overall pretty good. For example, the Harvard pilgrim Health Care medical/eye/dental insurance coverage are comparable with those larger payer's insurance, e.g., BCBS, Aetna, the premium are reasonable. Gym discount. Monthly parking cost assistance. The work hour schedules (including recently they upgrade PTO policy to unlimited PTO under manager's discretion) are flexible and encourage hard work hard play/relax (especially when you are working with the client, some periods of the time the working pressure could be much bigger than usual). If you are in headquarter, you will also have a ton of free food, beverage and snack. As a healthcare focused company, GNS also hosts Ping Pong tournament regularly. People here also have a reading club, a meditation club and a small instrument band. For me, as a remote employee embedded in client's side, I only have the luck to taste these elements when I visited back the headquarter but already feel they make the daily life more colorful.


    some of the software products need a better graphic interface rather than linux command line manner

    Advice to Management

    Maybe the name of "GNS" could be more generic/straightforward to represent the company's efforts in healthcare and precision medicine?

    Software Engineer Interview

    Anonymous Employee in Cambridge, MA
    Accepted Offer
    Positive Experience
    Difficult Interview


    I applied through an employee referral. I interviewed at GNS Healthcare (Cambridge, MA) in November 2016.


    Interview began with a screening phone call with the head of the department. Afterwards, I was given a programming exercise that took about two hours. It was of moderate difficulty. I think being prepared with an arsenal of dataframe-related tools helped.
    A couple of days later I was invited for an on-site interview. I had four one-on-one interviews that varied in difficulty. In the end, I would assess that I did really well in two, well in one, and in the other I did ok, as it was possibly the most difficult interviewee.
    Fortunately I was asked to provide list of references the next day. Two weeks later I received an offer.
    The whole process took about 4 weeks.
