There were four interviews if you count HR screening. With the four interviews I heard four different job descriptions. They don't know what they want in the role but they take people's time while they figure it out. After the four interviews, they asked to complete a BPMN exercise that must have been done by an intern. It had errors and was poorly formatted. This exercise took several hours to complete. It was not trivial. After sending in the exercise they went dark. No feedback. No response. It was probably for the better. I dodged a bullet. With an interview process like this, I suspect it's a toxic work environment. Good job Cartesian!
