Capgemini Sr. Consultant interview questions

I have given close to 7-8 interview rounds for different account. First time selection was done, documents were taken but offer was not released reason don't know not they had any courtesy to reply on my any mails inspire of numerous follow ups. Again after 6 months I was approached for the same role. Interview scheduled but no call came and this happened 3 times. Post which one round of interview happened with external client I was selected offer was rolled out but I asked for negotiation and that took 1 month to get approval and post which they said because your NP is 90 days we can't roll out new offer. I discussed with my supervisor who said I would be released in 60 days and same I communicated to CG HR. But they took another 20 days to reply and said sorry we have to drop you as client wants candidate to join in next 30 days. Horrible experience... Not sure if I could believe any HR anymore

Initially introduced by staffing agency on behalf of consultancy firm. Phone interview took place not long after that, with the supervisor in the firm. Afterwards had face-to-face interview with client supervisor on site. Had offer not long after that.
