    Configuration Specialist Interview

    Anonymous Interview Candidate

    Negative Experience
    Easy Interview


    The process took 4+ weeks. I interviewed at UL in January 2018.


    The interview could not have been anymore unprofessional. The hiring manager called me on his cellphone while transporting his child on a train in the afternoon when I specifically requested a morning interview. The call kept chopping in and out so I am certain he could not hear my answers to his questions. When asked for feedback he claimed my answers were too vague.
