SLB Business Analyst interview questions

It was a bad experience at business analyst post in Schlumberger PICT branch....The interview process is good...They take 5-6 interviews and then select the candidates...In my case I went through 2 interviews...1st was good and then the 2nd was too bad...in the 2nd interview the interviewer was too frustrated kind and had a bad tone...he asked only 1 quest and rejected me from interview process..I literally don't know on what basis the interviewer rejected me....though I gave an satisfactory answer for the question asked.!

The interview started with CV Screening , followed by a group discussion and then 1 technical, 1 management and 1 HR round. Then the offer is rolled out. Negotiations are rare.
