Capco interview questions

Ghosted by the HR named Angie and no updates whatsoever after 3 rounds of interview, especially after they find out more about my company and existing processes. 3 rounds of interviews process including HR round. First 2 rounds were HR and with head of team in Singapore, pretty alright experience. The 3rd round was with a director based in HK. He was 6minutes late for the interview and unapologetic, throughout the interview wasn't paying attention until he asked about challenges within my organisation. After that, there were no updates from them at all even after I sent two emails to HR checking on status. Very unprofessional and ghosting candidates like this. I won't recommend anyone to apply for this firm.
