Jane Street VBA and Excel

Hello,

I will be going in for an in house interview with Jane Street Capital. My recruiter specifically told me I will be tested on my MS Excel and VBA skill set as they use of a lot Excel on the floor.

To quote the exact words she said, "We will go to the trading floor where we will do something on Excel, VBA and order entries"

Now I know how to work with Excel and VBA, although I am not a hardcore VBA programmer. I learned the language during my internship and it is fairly easy to pick up if you know the logic behind programming.

What can kind of questions can I expect to be asked with regards to VBA and Excel? Do I need to know any specific functions, codes, properties, events?

Thanks for the help!

PS: I know the ask a lot of quant questions along with brainteasers. Im not worried about those as much.
