    Approves of CEO

    I have been working at NMS Labs full-time


    Excellent CEO - Cares about employees, treats them like they are people and not a body for the business. Is a true leader, listens and recognizes accomplishments.


    Like all businesses, some favoritism among supervisors. That can be detrimental to working environment - not always the best workers are given this privilege, but ones that can manipulate. Unfortunately.

    Advice to Management

    Investigate before taking informers word as gospel. There usually are two sides to a story and manipulators can unbalance and possibly cripple a workforce and eventually affect the company, as a whole.

    Average Interview


    I applied through an employee referral. The process took 2 weeks. I interviewed at NMS Labs in January 2016.


    Your first interview is with one of the HR managers via the phone, for about 40 minutes give or take. The second interview is onsite with the departmental supervisors. They are very easy to talk to, and very thorough in asking you questions that make you think. If you are well prepared you should do well. Be sure to tell them what you as a worker will bring to the company, as well as what you hope to accomplish in working for them.
