    Application Details

    I applied online. The process took 4+ monthsinterviewed at Johns Manville in November 2014.

    Interview Details

    Hiring manager was very genuine and a pleasure to interview with. Everyone else was either cold or acted as though they were uninterested in the interview or had no idea what they should talk about in the interview. The entire process - from the online application to the last step - was over 4 months. They do take their time! The company seems like a very good outfit. I rated this interview as "Difficult" because it took such a long time, and because several people I was to interview with were obviously unprepared, perhaps even caught off-guard and had no idea how to interview a candidate.
