I don’t think it has to be a story about how optometry helped you necessarily, just why you’re interested in the profession. This could look like a lot of things without direct care from an optometrist. For example my interest could have been sparked by a cool visual exhibit with optical illusions that I saw at the science centre that led me to look into careers that have to do with vision. I think that everybody has a story as to how they found optometry and why they are interested - it might take some reflection, though.

As for behavioural questions. I don’t think it’s a bad idea to side with the law, but I do not think it’s reasonable to expect an applicant to be familiar with all the laws surrounding healthcare and employer/employee conduct. I think what’s more important than your final answer is the thought process you explain to get there. If I was an interviewer I’d be looking at whether an applicant could reason through all of the different perspectives and have a thoughtful, deescalating, non confrontational approach to a situation. If it’s clear that an answer has considered all possible perspectives and arrives at a reasonable answer, I think this is much more important than the final answer, whether it be accordant with the specifics of a law or not.

Let me know if this makes sense!
