I first received a phone interview from Schlumberger. The phone interview consisted of questions such as 'describe a time when you had to put together a project in a short amount of time, explain what you did and how.' Then we talked about Schlumberger's business units. I was granted a second interview in March and had a group presentation on the first night. They then broke us into teams and assigned us a series of tasks while moving people in between teams to see if we could complete the task with distractions. The next day was the field visit during which we had brief one on one interviews. I received a call for a third interview.
