I was contacted by a recruiter who told me to apply to one of two specific positions online.

I had two phone interviews the following week and they flew me to LA for an in-person interview the week after.

The in-person interview begins with a 20-minute presentation about your first or second most technically challenging project to a number of team leads. They will grill you about this project and various aspects of it for about 30 minutes.

They will then discuss if you should proceed to the next phase.

If it is a yes, you will then meet with each of them for 30-minute one-on-one interviews and answer their questions.

At any point in this process, they may decide you are not suited, and the recruiter will escort you out.
