Interview process is a full day of interviews where they focus on technical and behavioral traits of the candidate. It was a series of smaller interviews about 1hr each where most of the interviews would be conducted with two people each time. Depending on distance from location, there might be a dinner interview the night before for the candidates that flew in for their interview.
