I used to have a favourite scenario that I used to ask testers:
Scenario 1: It’s Friday afternoon and a product owner comes to you, a little stressed and askes. I know it’s Friday afternoon and there is only 4 hours left of the week, but we have had this change that we have done for a customer and you are the only one that knows the product. Could you have a look at it and give me your feeling for it before we give it to the customer this weekend?
Scenario 2: Same person, same product, same change but instead of Friday afternoon you get it Monday morning and instead of 4 hours you have the entire week.
If and how is the 4 hours in the Friday afternoon different from the first 4 hours on Monday morning?
What I am looking for is how you view your job as a tester, there are no right or wrong here.
Another scenario is:
Simple web app with web page with an input field, backend with database where the value is persisted. Identify all the boundaries for this scenario.
This being said, one of my favourite recruitment moments was where we had a test application that had 28 known errors in it and you were to test it. One of the applicants said, I won’t do that. I’m here to do performance testing, this is not relevant to me. He was hired!
