Medpace CTM interview questions

Face to face interview following phone interview. I was supposed to meet with Directors and CTMs but only the CTMs showed without even apologizing for no show up from directors. I was asked to prepare a 15 mins presentation on ATMP and spent many hours to prepare it. At the interview I was cut short because they said I did well and they just need to check if I can present which was quite upsetting. I was asked question and while answering they would ask another question not allowing me to finalize my answer. Overall, I felt interviewers were unprepared, in a rush and not appreciative of the efforts in my presentation and showing up. Even after the interview I didn't hear from them even after I emailed to follow up. A major let down, not recommended!
