MELBRO..
expect behavioural type questions.. (tell me about a time when)
things like
Customer Service(a time when you delivered exceptional service or gone above and beyond or even recovered a customer)
Safety (a time you reported something hazardous or saw something that was unsafe..what did you do?)
Teamwork (working within a team or even had a difficult team member to deal with)
Conflict Resolution
Company Protocol (a time you've gone against it)
why you want the job? what you know about qcca? what sets your application above the rest of the field?
hope that helps.
