    I worked at John Zink as an intern (less than a year)


    Very nice people, great pay, plenty of work to do, very challenging assignments, excellent work-life balance...

    The CEO isn't some figure in the sky. He's at the office all the time, and he takes the time to speak with you. As an intern, I spoke with him for 20 minutes about school, life, and things to look forward to in engineering.


    Did not have much time to train me on specific parts of the field.

    I had no field opportunities as an intern. It would have been nice to see the project I was working on.

    Application Details

    I applied through college or university. The process took 4 weeksinterviewed at John Zink.

    Interview Details

    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.
