Interview Preparation Tips

Round: Test
Experience: There were totally 8 sections to the test. But they could be broadly put under 4 categories. Firstly all questions were compulsory to attempt and there was no negative marking. Aptitude: Basic quantitative math questions were asked. There was one simple programming question where one could code in C/Java in your local IDE and upload the code file. It was a DO or DIE question, either you get the question and proceed to the next questions of the test or the test gets stopped if the code is not successfully compiled within 5 attempts. This programming question, as was told was an important criteria to filter out candidates for the next round. There was a descriptive question asking about a recent team project done.
Tips: Achievements in sports and other extra curricular activities are valued. Mention them in the resume, if applicable.
Duration: 1 hour 30 minutes

Round: Technical Interview
Experience: In this round, they look for the candidate's experience in coding in whatever language mentioned in the resume - I was asked to write some simple codes in c. I was also asked to explain some projects from the resume.
Tips: basic knowledge of data structures, resume preparation

Round: Technical + HR Interview
Experience: In this round, the questions were mostly based on the resume and the projects done. Also, HR questions like What do you know about Schlumberger, How do you perform in a team, What makes you unique from the other candidates etc. were asked. They also ask if you have any questions from your side - Better to ask questions if you have one or if you can't think upon any specific question, ask them a doubt from whatever they have said(usually they say a lot about their company and principles before they ask you for questions)
Tips: Prepare for a HR interview separately, resume preparation
