I applied through an employee referral. I interviewed at Mindstream Interactive (Columbus, OH) in Jan 2020
Interview
Two panel interviews in person that lasted about an hour each. 2-3 people per panel across a variety of digital marketing disciplines were present and were there all at once instead of one person at a time.
It was a fairly typical interview process. Met with five or so people over the course of two visits to the office after conducting an initial phone interview with HR.
