SoCalGas Rotational Program for Associate Engineer interview questions

I had my group panel interview in early April. The questions had nothing to do with engineering and were more situational and personality questions. The people didnt seem interested from the being evn though i had a 3.5 gpa and had applicable internship experience. They did not pay attention to my responses and the hr people there are really fake and unprofessional. I emailed the hr department to get an estimate of a timeline of when canadiates would be informed of there choice but to my surprise they did not respond and after a month and half i recieved a rejection email. Overall the interviewers were rude and the HR department completely unprofessional.
