    Good Management with routine expectations of what needs to be accomplished. The work environment was self-paced without unnecessary micromanagement, as well as understanding and friendly people to work with.


    As in any corporate company as large as John Zink, some areas are managed better than others. It really depends on the department you are working in. That is to be expected in such a big company.

    Advice to Management

    The internal hiring process seems to be lacking - there was quite a bit of people told the same thing in positions coming available (You've got the job, you will be hired, etc). For those that had families depending on a job change- that can be devastating to not get a job, I imagine. Just being forthright about the possibility of a job would be something to improve in departments that need it addressed.

    Positive Experience
    Easy Interview


    I applied through college or university. The process took 4 weeksinterviewed at John Zink (Tulsa, OK).


    First round interview: on campus, about 30 min. The interviewer asked questions about my resume, then moved on to simple behavior-based questions.

    The second round took place at John Zink and included a plant tour and lunch. There were three consecutive interviews each last 45 minutes with 2 interviewers in each interview. The questions were slightly tougher behavior based questions, with a emphasis on demonstrating how you live out the Koch Industries Guiding Principles in your life. There were also questions regarding which section of John Zink you would like to work (I.e. Flares, burners, etc.) and your plans for the future.

    Overall, everyone at John Zink was friendly, accommodating, and knowledgeable.

    No pay negotiation. However, if you do not live in Tulsa normally (or are a student who would have to pay extra to stay in Tulsa over the summer), you can ask for their relocation signing bonus, which is $1000.
