They sent homework question to pass before an initial interview which lasted around 30min. The homework questions asked about interest in the position, how to problem solve, work styles, etc.
I interviewed at The Kaizen Company (Washington, DC)
Interview
Two interviews - one more formal and another over the phone to ask remaining questions. The first one was with two individuals (HR, and someone who has the role I was interviewing for)
I submitted an application online and was contacted quickly for a phone interview. The interview was a one on one phone call with a current Program Coordinator at Kaizen. I was only asked 3 questions. It was all very quick.
