Technorati interview questions

The questions were very straightforward the issues I had were with the lack of communication after the excessive amount of phone interviews i had. I had an initial call with HR and then 4 more calls with Directors and VP's and then the communication line went dead. I waited around a week before reaching back out to see what next steps if any would be since I was told they'd get back to me after my last call to set up an office visit. I emailed and called the director about 3 times and HR about 2 times and never got a reply back. You'd think after 5 interviews Technorati would be professional and someone would have reached back out telling me they'd gone another direction instead of wasting my time. Very Disappointing experience.
