There were 4 rounds of interviews, 1 was a call in. It required 2 vacation days to come in to the office. You will interview for various positions at the same time, which can be a bit nerve wrecking, but also can help you as you have multiple options. Interviews will occur over multiple months and multiple times. They are both in person and phone interviews. You can see 5 people each time or less. The organization is conservative with 4 levels of roles. Everyone has input and earns their merit. You need to be a team player and like the fast pace corporate life to be a candidate of superior quality for them to consider.
