Experience: I don't know what to name this round, but it focused mainly on developing test cases for an object. Say they gave me a stapler and said to develop a test plan listing down test cases for a given object to pass so that it can be confirmed that it is a stapler. Another scenario was with a lift.
Tips: This is one round where your presence of mind and inter personal skills matter. I think the way you present your thoughts was most important here.

Like your assigned work could not be completed on time, or if you are doing something wrong with the work assigned.
