Wood Mackenzie interview questions

It was a 3 stage interview: a phone interview with the HR, then a face to face interview with the hiring manager and then a conference call with a director. Interview at each stage went well. However, 2 weeks after my final interview, I emailed the HR contact to ask whether she could let me know if a final decision had been made with my application, I never received a reply. I followed up with a second email 2 weeks later but never received a response. I thought it was incredibly rude and unprofessional since I went through several rounds of the interview process and wouldnt want to work for an organisation that thinks this sort of behaviour is acceptable.
