is the format my company uses against 'Capabilities'
The interview questions usually go like this (the applicant knows which 2 of 7 capabilities will be covered, so has time to prepare..)
Can you give a recent and relevant example of when you demonstrated *good customer service* (or other capability)
The advice I was given was that any action must have a good reason or why would you do it, and also always say 'I' instead of 'We', even if you were part of a team.
Also word the objective as simply as possible. if there are multiple elements group them together into a single phrase.
Aftermath is about reviewing the whole scenario and seeing if there was another way in which the outcome or result could have been achieved.
Scenario's don't always need a successful outcome but you wouldn't want to use a failure as an example in an interview, would you?
..oh and like Yoda says, 'Do or Do not, there is no 'try'''.
