Salesforce Customer Success Manager interview questions

I initially had a phone screen with the internal recruiter, who suggested I have a one on one interview with the hiring manager. The following week, the recruiter informed me that the hiring manager wanted to meet me in person. Aproximately 2 weeks later I was asked to complete a presentation for a "Case Study". He emailed me the details of the case study and I spent seven days preparing for it. Approximately 2 weeks later I was advised by phone that the role had been given to an internal candidate. A week after this I was contacted and advised that the company had increased head count and that because they were very interested in my background they wanted me back for a further interview. The following Monday I arrived at their office for a Video hook up with their VP and Hiring Manager to be advised that the meetig was cancelled and re scheduled for later that week. Having waited 3 weeks after this video conference interview I was advised that I was to partcipate in a telephone conference call with their MD of UK who managed the Asia Pacific region. Following 2 postponements the date was finally set. O the day of the final conference call I sat on the phone for ten minutes waiting for the MD to join the conference call. When it was apparent he would not show I rang the internal HR and they advised they had just received a email cancelling the conference call. However, the next week came and went with no update. The following week, I sent an email to the HR recruiter and did not receive a response. A few days later, the HR recruiter advised he found my email in his Junk Mail and that he was still trying to arrange another conference call. Following another 2 weeks I sent another email which bounced back with HR recruiter on anual leave. When I rang the HR department I was advised that all roles had been filled. Having spent 3 months going through 6 interviews including a case study and then being asked to attend a failed conference call and then to be told that there are no jobs anyway?It is shocking to me that this is the way that Salesforce.com does business. I guess I should be relieved since I imagine this is symptomatic of how they treat their employees and customers. This would be the worst process I have ever come across for the way candidates are treated.
