NTT DATA interview questions

Applied through an agency to a consulting role. process took 3+ weeks, 2 stage process, first with a member of staff and the final the Head of the division in the last interview with the Head of division i've found very a awkward interview with the guy doing personal questions, disbelieving my CV, making comments to my person and talking assumptions. Was the worst experience in my career regarding a interview process.I really can't imagine if they are bad in the interview process how can it be having those guys managing me. The managing guys from consulting are very weak and not very smart professionals. I really don't recommend anyone to apply to this company.
