Capgemini Invent Salesforce Business Analyst interview questions

I had a telephone interview which lasted 45 minutes. 3 months later I had a second interview which I took a day off work. I got a Train to the interview. They gave me the wrong address for the interview. I then got a Taxi to the new address. The interview lasted approx 1.5 hour. 3 months later I had a third interview, Another telephone interview. Which covered more General questions. I spoke with the Recruitment Consultant on a weekly basis and was told the job was mine but Cap Gemini HR were holding up the offer process. 10 months later, I'm still waiting. No more phone calls from the Recruitment Consultant. A horrible experience and disgusting way to treat people.
