Had two phone interviews. The first interview was with a team in Columbus, Ohio. The second was with the Ohio and Iowa teams. My third interview was in person with a team member, team leader, and an Ohio manager on the phone. The interviews went well. They requested a portfolio and Coding Challenge. We reviewed the challenge on-site but it is a fairly extensive challenge (they want you to build a website). I would definitely interview there again. Really enjoyed the atmosphere and team.
