    - "What's your greatest weakness?"
    - "Honesty."
    - "I don't think honesty is a weakness."
    - "I don't give a damn what you think."

    Convert 10-psig to feet of liquid (SG = 1.0)  Convert 10-psig to feet of liquid (SG = 1.0)

    Calculate the duty (in mmBtu/hr) of a heat exchanger with 1,000 gpm of a process fluid cooled from 150⁰F to 120⁰F?
    (Assume SG = 1.30 | Cp = 0.75 Btu/lb-⁰F)

    If the coolant in question #2 above is water, what is the LMTD of the HEX?  (Assume Counter flow | CWS = 60⁰F | CWR = 95⁰F)

    One of the typical sizes of an API 12D tank is 500-BBL.  How many gallons of product can safely be stored without overflowing?
    (Assume the tank has a live volume of 80%)

    What is the equation for Reynolds Number (as defined as ratio of inertial forces to viscous forces)?

    Specify the most economical pipe schedule for a typical 8" NPS CS class 150 service?

    Good ones, Corey, but it's a job interview - not a PE exam.

    I have found over the years that engineers can hide their incompetence by using their personality and charm.  This will come out naturally during the interview process regardless of the method used. The market is challenging with little forgiveness to allow for OTJ training.  When I switched from a personality type interview to a more skills based interview, the quality of my hires improved along with retention.  Granted the number of candidates interviewed per hire increased 3-fold.

    I doubt if most undergraduate ChEs or their professors could answer these questions on unit conversion and jargon.(or graduate ChEs)

    Totally unfair

    Hi,

    They may ask technical questions related to process designs (pump specs,  relief valve sizing, separation techniques)
    Also questions related to process plant troubleshooting
