My strange adventure with the Inttra Corporation

I had before March 2010 never heard of the Inttra Corporation. In that month I received an email from a recruitment officer working for them - they had a vacancy for a European based EDI Specialist.
I am a very experienced EDI specialist, I read through the requirements and decided to apply.
I spoke to the recruitment officer a few days later. He liked what I had to say, and my CV obviously fitted the bill, so I was informed that I would hear from the department concerned over the next few days.
I spent a lot of time reading up on who the Inttra Corporation were (a major international player in the ocean shipping industry, with headquarters in New Jersey in the USA).
I then proceeded on a series of telephone interviews with them - nine in total.
If a company does not like you, they are not going to have nine interviews with you. I liked the sound of the job (I could work from home and visit the company's European clients when required). Everything seemed to be going remarkably smoothly. I was confident that I would be an excellent fit, and my professional expertise would be appreciated. I was also not looking for a stratospheric salary.
After these nine interviews (over a period of six weeks), something very strange happened - all contact between us ceased.
If they did not want me, if the vacancy had been filled by someone else, if they had put the vacancy on hold (something that often happens in recessions), you think that I would have been told.
I sent emails asking what happened - they went unanswered. I made telephone calls to the numbers that I had been given - all I got was voicemail. I would leave a message on those - nobody came back to me.
Surely they could have at least managed "no, sorry" if that were the story .....
From the start of May, I heard nothing at all for five months. Then in October, the recruitment officer came back to me and asked me if I were still available and still interested. I wrote back that I was still very interested, even if I were a bit surprised by the lack of information that they had given me regarding my application previously.
Seemingly in keeping with the way things have proceeded with them, I got no reply to that email either.
I have applied for so many jobs, both real world, and internet-based organisations like Freelancer, Elance and ODesk, and I can tell you that the rejections hurt. With all this talent and experience I should be capable of doing a great (office) job for someone. And I am fully aware that ageism is the root cause of a lot of these refusals.
But seeming indifference and lack of information like this?
Why interview me nine times? And then leave me (as keen as I am to get working) sitting around not knowing what is happening, or why did events take this turn ....
I see no sense in it.
