    There are many potential groups to work in here for a technically skilled person. It's not like you are locked into a particular job, so there is a lot to do for someone new to the industry.


    The company is growing very quickly and it is straining the space available in Seattle and San Jose to the point where employees are getting less space. They're being moved around. It's not a huge deal, but it's noteworthy.

    Advice to Management

    Hire more interns and entry level test engineers and developers. Don't aim so high all the time for Senior+ roles.
