depends if you're going for GSA or GSTL. GSA has 3-5 situational questions about leadership and team work. 1-2 interviews Think of specific examples where you had to work as a team player or lead a team or process. Usually asks for a specific example instead of general overviews. GSTL is the same thing except you have to go through 3-4 interviews with possibly 2 ETLs, STL, and some districts the DTL.
