They will ask a bunch of situational questions. I have been trained in interviewing and all you have to do with every answer is use the STAR method. Situation, Task, Action, and Result. Also try to find out from an employee what the possible rates of pay are. There is a high medium and a low for every position. Also there is a different rate of pay for each market. I think DC and San Francisco are the highest at GEO 0. Then LA and other big cities are GEO1. There are 4 GEO codes all togeather so make sure if you get info to check on what GEO code you are in.
