I applied in-person. The process took 2 weeks. I interviewed at US Postal Service (Merrifield, VA)
Interview
Face-to-face interview with 3 managers. Some "quiz-like" questions were asked and also a discussion of prior experiences and relevant projects. Each interview was specific to the manager's own style so individual questions and interests in factors important for the position varied with their purview of responsibility. The interviews overall were very straight-forward and direct; no real curveballs.
Interview questions [1]
Question 1
Describe how you've applied skills relating to programming, simulation and modeling, and statistical analyses.
