The interviewing process was overkill, which is why I turned down the initial offer. I was invited back for five separate interviews, before a panel interview. I received a phone call a few months later, inviting me back for another interview. I negotiated a higher starting rate, to leave my current employer then. Behavioral based questions, taken directly out of a corporate interviewing guide, e.g. give me an example of a time you had to perform a task that you did not agree with, STAR style answer is expected. Different categories were Maturity, Conflict resolution, Adaptability, Lean Six-Sigma, and Management style. Panel interviews consist of whoever is in the building at the time, e.g. Operations Manager, Financial Controller, Credit Manager, Inventory Manager, Warehouse Manager/Supervisor, and even the front office gal if they are short interviewers.
