I was introduced to the company through a friend of mine that knew I was looking for a lab position. He introduced me to an employee that passed along my resume to the hiring manager, who called me a few days later to set up an interview. It was 1 on 1 and fairly routine. Some of the interview was technical, but most was behavioral and consisted of hypothetical questions gauged to see how well I could be a team player while still being able to work as an individual. The manager gave me a tour of the facility and introduced me to some colleagues, some of whom were management and others that were not. Zep is a good company from what I saw that had high standards of quality and needed its employees to be part of a team at times and work individually at other times. Please note that you are being judged at all times. Be nice to everyone you meet, from receptionists to hourly floor workers, to upper management.
