How did you justify your salary in your current job?

• I replaced two people for a period of two years in the largest department.
• Very simply, I was paid by volume of production [or I was paid on a commission basis].
• My objectives were very clear, and I often worked overtime to meet them.
• By ensuring that over 50% of the consumer base remained loyal to the organization.
• I took my responsibilities seriously to make sure nothing went wrong [for example, production never had to be stopped].
• I did my job with heart and I succeeded in ... [mention one or two achievements].
• By generating a contribution that was five times the size of my salary.
