wa salaam Oasis_asu,

I've conducted interviews in the past. Some questions my team and I usually ask are:

What are the differences between a datareader and a dataset?

What would make the most logical sense, binding a dropdownlist to a datareader or a dataset?

What are the various template tags in a datagrid and what are they used for?

For a datagrid, which event could you use to populate a dropdownlist and set it's properties if the list items were dependent on data you were binding to?

hope this helps!
