Third Bridge Client Service Associate interview questions

Applied online. Heard back quickly and had an initial interview. The interviewer was really friendly and took an interest in personal and professional development. Questions were competency based but not the basic type. They had a bit of a twist and were a bit contradictory so be able to remain calm and think on your feet even if you have prepared answers. They gave feedback in an email afterwards which I appreciated.

I submitted an application and received a link to select a time slot for an interview (and got a confirmation email for that time.) On the day of, I waited around for half an hour after the scheduled time and nobody showed up. I replied to the initial email to ask about a rescheduling, but nobody responded to that either. I know someone who works at Third Bridge who helped me figure out what I would say in the interview. He was shocked that this happened and gave me the interviewer's work email so I can ask him personally about the situation. I sent two emails over two days. No response. So, I clicked the original time-slot link to schedule an interview again. He showed up this time, but did not apologize for missing the first interview or acknowledge any of my emails. He was also a bit awkward. He asked me one of the questions twice and made a couple comments about my answers that didn't make any sense, like he wasn't paying attention. He was also ambiguously condescending at times. My rejection email came a few days later with no feedback. I have a very good grasp of the job and company through my connection. I graduated from a top-20 university and have a lot of experience working in client facing/consulting-related jobs. I genuinely believe I am qualified for this job and deserved a better interviewer. I'd ask for feedback, but I have hard time thinking anyone would reply to me. I am so disappointed in Third Bridge. I really thought this job was a great fit for me.
