The whole process took about 1 month. I applied online during my university recruitment and they called me for an interview in ~1 week. The interviewers invited us for a meet and greet the night before the interviews. We had appetizers and were able to ask them any questions we had. This was helpful because I got to meet the people that would be interviewing me beforehand. Pretty standard personality-based interview questions. Had to describe faults, beds, trap styles, regional setting, etc. in a seismic line at the end. That was a bit difficult, but they gave me a couple hints along the way. I received a call about a month later offering me the position. They gave me a week to decide whether or not to take it.

The interview process was long consisting of approximately 7 stages. First few stage were online tests and one way interview. Next was a technical interview that was about an hour. half was a chat about what I've done/learnt in geophysics and the other half was interpreting a seismic section. Final stage was assessment day that consisted of group challenges, written and interview challenge on bp's current projects
