The process starts with a free design work , the second interview took 4 hours, a candidate needs to speak to 5 people in a presentation of the free work they asked and separately with each person. They barely voice their concerns and moved on to separate interview. During each interview, some framed high level questions about collaborations and organizations, some framed a high level question but forcing for granular answers. However, most of the feedback is highlighting how do they feel , not facts I answered, probably because they didn't take notes. There are also some sign of lack of experience and poor communication skills within engineering. The interview is probably more suitable for a junior who is still learning the basics and love free work.
