    Easy Interview

    Application

    I applied online. The process took 3+ months. I interviewed at Westlake Chemical (Lake Charles, LA).

    Interview

    The interview was more standard personality question based with very little on the actual duties even when I proceeded to ask. The overall atmosphere was very pleasant and cozy as one would expect in Louisiana.
