    I have been working at Sentinel Technologies full-time (more than an year)


    Time Off when you need it. Managers don't breathe down your neck. You get to work with some of the biggest household corporate names in America.


    Internal ticketing and dispatch needs a little face lift. Sometimes the system is a bit counter-intuitive, but you get used to it.

    I applied online. The process took a weekinterviewed at Sentinel Technologies.

    Interview Details

    This was the most negative interview experience I have ever had. The interviewer was extremely unprepared and had clearly not read my resume, yet from the beginning of the interview she seemed determined to cast all of her questions in a negative light. She barely responded to my answers; nothing seemed good enough for her, even my answer to her first question. Why even interview someone if you've already made up your mind for whatever reason? I would never work for this company just based on that terrible interview experience.

    Interview Questions
    • The only unexpected aspect of the interview was that the interviewer was so unprepared. She didn't even know where I had gone to school, and that is at the top of my resume. It was ridiculous.   Answer Question
