    I have been working at Castlight Health full-time (More than a year)


    - I get to work for an industry leader in technology in a market that desperately needs our solution - I have 'all' of the resources and internal support needed to exceed expectations in my role - I get to work with the smartest and hardest working individuals in the industry - The technology we sell is literally 'light years' ahead of our competition - I am in a position to help positively impact one of the greatest drivers of the U.S. Economy - I help U.S. businesses compete on a global scale, reduce costs and attract top talent - We are disrupting the healthcare industry with a cutting edge technology that is fundamentally changing the market and the way companies will manage their healthcare business moving forward


    - There is no standard template for closing deals and winning new business (You must be able to 'create' innovative solutions to complex problems involving multiple stakeholders) - Our technology is a few years ahead of the market (salespeople who prefer to make their quota on low hanging fruit need not apply)

    Advice to Management

    Thank you for creating a culture where the entire organization from marketing, product, engineering, customer support, executive management and alliances are set up to support the sales team. Never before, at any company have I felt like I have all the resources I need to be successful at my disposal.

    Easy Interview


    I had 2 rounds of technical interviews and a behavioral interview. The interviews were very casual. The questions were not difficult. It required a bit of thought but were answerable. It included data structures, algorithms. Anything up to graphs in DS seemed to be what they were looking for.
