As the Hill Start is somewhat redundant in an Automatic they may get you to perform a gear change instead. You can actually select gears in an Auto, even if it is just Park, Reverse, Neutral, Drive, Low. Some cars will actually allow you to select 3, 2 & 1 instead of Low. Would you believe there is a right way and a wrong way to do this.
These two gear sticks have one major difference, the one one the left has a pattern to it while the one on the right is straight down and up. The problem with the straight selector is that you can easily move straight from S into R by mistake. To prevent this the gear stick has a button which will stop the stick moving from N into R. The examiner will want to see that you DO NOT use the button to change gears unless there is a gate.
