CGI Program Manager interview questions

2 technical interviews and 1 hr interview. Applied for the position through an internal referral. All interviews went well, great chemistry with both interviewees, passed all technical and behavioral questions, and full alignment with hr requirements. Discussions and empty promises led me to believe that I was expecting an offer and a great future with the company, and ended up receiving a rejection email out of nowhere. Sent a follow up email to understand the reason for the outcome, and obviously no response... Absolutely the WORST company I have ever interviewed for, extremely unprofessional, unbelievably disrespectful, wasted my time and effort, no budget, no vision, no structure, and no internal alignment! SAVE YOUR TIME AND STAY AWAY AT ALL COSTS!
