First round interview was with People Operations in NY. Typical competency interview, with strong focus on leadership skills and the usual tree-planting example. Next round was a situational test where I had to develop a solution to a data collection issue, and list what tasks I would do having been assigned a temporary Logistics Manager position. The next interview was with a field office, 1.5 hours long and very intense, including a case study on expansion of OAF operations into neighbouring communities. I would say they focus intensely on leadership skills and experience, so make sure you have tangible examples of how you have effectively led a project/team. This was what I believe was my main area of weakness. The overall experience was average - could be better in informing candidates they were unsuccessful (v slow response) & no feedback given.
