I have some good idea that will be useful for you. The STAR approach. here it is,

S= discuss about the situation, the background situations and the like. for example "when I was in "X" organization working as "y" job title..........

T= the target; what was the objectives/targets you were responsible to ahieve working in "y" job title

A= what was the activities, actions, skills, behaviours ......that position required

R= what kind of result achieved, success .........
