Capgemini Director interview questions

I was approached by email by senior recruiter who had viewed my LinkedIn profile, initial 'phone discussion with recruiter to establish my potential interest. Full job spec supplied after I confirmed possible interest in the role. As the role was biased towards innovation I submitted my resumé as a PowerPoint presentation, in the expectation that my presentation would be close to those I would have to deliver in-post. This was favourably received and I was invited to a formal interview. The interview went well but I realised that my decision to wear an expensive suit, shoes, collar and tie did not mirror the interview panel, who were all dressed for business casual. About ten days after the interview, the senior recruiter called me and ran through a whole list of praise for my experience, skills and interview performance - summarised as being excellent. But then came the killer punch: "we consider that your management presence is not congruent with the needs of the Center." So, in their words, good enough to do the job but didn't look the part. My conclusion that it was probably my smarter attire, when they expected business casual dress. Or it could have been my age (mid 50s) which, of course, they could not cite legally as a valid reason for rejection.
