TE Connectivity Product Development Engineer interview questions

In initial discussion it was told that role is for manager but on interview day I found they are interviewing for engineer role. They took 3 rounds of interview for more than 3 hours. First round was related to my experience and few technical question. Second round was CAD test. Gave me 3D CAD file on 1 screen and on other screen asked me to create CAD and drawing. The CAD model was not simple and time provided was not enough to measure the dimension and create geometry. During that test itself 1 more interviewer came and started asking me lot of hypothetical questions which were irrelevant for the position. Within 1 hour the CAD interviewer came and after analyzing completion level of model asked me why you were not able to complete? Even though he knew that other guy asked me lot of question during that 1 hour. This is worst level of unprofessional interview I have ever given in my career.
