Smashing Ideas Senior Project Manager interview questions

Was contacted by their HR department. Scheduled 30 minute phone call which turned into a 75 minute call. The HR rep was very enthusiastic about my previous experience and said I would be a great fit with their company. She was to set up an interview with their Program Director. After a couple days of not hearing back, I reached out to the HR rep again. She said she was sorry that she hasn't been able to schedule a time, but she would do it with in 24 hours. After not hearing back again, I contacted her two days later with no response. I then let a week go by and contacted her again, and like last time, never received a response. It's been almost a month now and I've accepted a job elsewhere. I think it's quite unprofessional for their HR rep to never respond to emails or phone calls, especially when they acted so interested in my candidacy.
