Publicis Sapient Software Engineer - New Grad interview questions

One of the worst recruiting processes I've been through as an almost new grad student searching for SWE roles. It was a very long and inefficient process to arrange interviews. On the first behavioral interview, the interviewer was about ten minutes late. I moved forward to the next interview, and the interviewer didn't even show up. We rearranged another interview, and the interviewer failed to show up again. I felt like my time was wasted and not valued, and I found it highly unprofessional how interviewers don't even show up. Very disappointed overall.
