Company's in-house recruiter contacted me on the phone and set up face-to-face interview in a week. I was local. In the interview I met with 2 design leads and 1 director. Did introduction on some of my work samples in my portfolio. Did a usability testing on-the-go exercise on one of their client's e-commerce website. I assume this was not a premeditated question. So I don't know if they will ask the same question again. It depended on whom you are meeting with. If it's an Interaction Designer the exercise could be on designing.

Straight forward, all was remote, 1 on 1, small group (2 ppl) and group interviews (5 ppl) generally casual, but in depth questions and conversation around process, the type of work I'd like to do, and how I would bring value to the team. No assessment or design challenge.
