That title sounds strange, but I’ll try to explain what I mean.
Many interview questions are designed to make you think of an example story to demonstrate a particular competence. Then there might be follow up questions about how you dealt with the challenges along the way, and then perhaps in retrospect whether you’d have done anything differently.
So the point is that even though you can’t predict the specific question, it’s a good idea to think of a few examples of your most interesting professional experiences, and really analyse how you acted along the way – and then practise telling the story (see my previous post about rehearsing in front of friends or the mirror) – always bear in mind that these stories should demonstrate skills that are relevant to the role of being a lawyer.
And finally, yes, it’s OK to have made a mistake and describe it, as long as you have the self-awareness to realise that it was a mistake and show what you have learned.
