Barclays interview questions

This is the worst interview process I have had in my life. I had more than 14 interviews during 9 months, in a process that they call CIDS. At the end, they made an offer with much worse conditions than those initially described in the job description. The conditions of the job were changed several times during the process, they asked for every detail of my life, since when I was a kid to any single personal dissapointment in my life. You can't imagine how deep they went emotionally, and I was expecting that at least the salary was going to be worth the effort. I was interviewing for a Manager role at the corresponding salary, and at the end they offered a Director role at a salary level below Manager, which clearly wasn't a fair deal, was it? This means that they wanted me to do a Director job but at an Analyst salary, and this wasnt what they described at the beginning. To justify their change in conditions they put a headhunter in the middle and said that it was the headhunter's mistake which is sounds very ridiculous to me. In short all the process was perfect to offer the worse salary possible, and it is very difficult to believe that a company such as Barclays would have made such a big mistake after 14 interviews. Clearly I declined the offer, as this didnt give me assurance that they would respect any aspect of the job in the future. I will honestly not recommend this Company to anyone, and will prevent anyone to apply.
