Depends on who is interviewing you - lots of different styles.
Depends on what role you have. Warehouse and Production staff - show up, do your job, go home - pretty laid back and chill. Office staff - because you are more visible to upper management, you have to fake loving what ever hype they are selling; 'Love organic', 'I bike everywhere', 'I do pilates all the time'. Just hearing the stories they told about working up there, and what they had to do to keep their jobs, glad I worked in the warehouse/production side.
