SLB Supervisor interview questions

Phone call from Dubai with a nice/easy lady who checked my command of English and call ended up with agreeing on a technical test date and a form of questionnaire to be filled by myself and sent to her. On the inteview date the technical questions arrived from the region and I went through an intensive tech. test that I aced after a month of preparations. I was then introduced to the technical gentlemen who interviewer me and one of them was a big nose. I left with average impression and a little feeling that they intentionally didn't appreciate my experience for some reason ( I didn't like this part and so I opted to head to another employer).
