I had two interviews. The first was with the communications team, and the second was with the specific team within the "system" I applied to join. Both were pleasant. The first interview was more of a screening conversation - it felt casual and focused on company culture, TEAL, etc. The second interview was more challenging: I prepared and delivered a presentation, followed by role-specific questions. They had several delays in getting back to me between rounds, but these were generally communicated.
