They use the STAR method in the initial interview, Situation, Task, Action, Results (look it up), although not everyone is well-trained in it. The emphasis is on your experiences with teams, especially leadership roles, and how you handled conflicts or other problems that arose amongst team members. So, know how to describe these kinds of situations succinctly and clearly. Soft skills are very important for technical positions, so one needs to find a balance between describing their soft skills as well as technical skills. Interviews on site with members of the staff can be more free form and depend on the interests and personality of the individual.
