I interviewed for two positions and they had very different interview styles. As a contracted employee, the interviews felt short and that I didn't necessarily get a view on what the job and culture would be like before I accepted the position.

Hiring process is more or less straightforward. However, one key point is that it takes time to conduct the background check and general security clearance. Straight forward interview. Questions about how your resume/experience fits the position. Likely you can expect to address a scenario: describe your analysis approach and your proposed deliverables. Expect additional questions regarding how you would manage stakeholders, address change management and scope creep.
