Trinity Consultants Consultant interview questions

Following an on-campus visit, we arranged an in-person behavioral interview. I was invited to the 6-hour final round of interviews (including 45 45-minute technical writing section, and 4 behavioral interviews). I received verbal offers from two offices, and called with both regional managers. They both said an official offer would be sent to me in a week or two, but it never arrived, and I heard nothing. A month later, I emailed both managers, and I was sent a letter of rejection. This company is significantly less professional compared to other places I have interviewed at and received offers from. On top of that, they expect employees to work a minimum of 47 hours a week for very uncompetitive pay. Overall, a bad experience from a subpar company.
