Codility Sales Development Representative SDR interview questions

Reached final stage interview (6 stages) and received no feedback or offer. I sent an email asking why this had happened and received no reply. All interviews were 1:1 and 1 hour long conversations. I reached the final stage and spoke to 2 managers in less than 30 minutes. They didn't seem very interested in speaking to me and asked me to drop any question via email, which was very odd. Never heard back from any representative at the company.
