There were multiple HR screening interviews, and then two interviews that focused on functional consulting and technical skills, Then they asked to complete an assessment that took about four hours to complete. After all of this, there was zero additional communication, feedback or even acknowledgement of the completed exercise. It's disappointing to be ghosted regardless of the outcome. A small gesture can bring closure. Hopefully this isn't an indicater of the larger culture but Cartesian does need to improve in candidate communication.
