Positive interview process. First stage was a 1 way video interview. This was a little stressful beforehand but the questions were easier than I had expected. I then had an informal video call with the hiring manager where I could ask questions. The final stage was a 1.5hr technical interview with 3 people from CGG. Here you had to deliver three 5 minute presentations: 1 personal, 1 on your past research and a final one on a CGG technology. At the end of the interview there were some basic seismic imaging/seismic data questions which you should manage with problem solving knowledge and from your research into the CGG technology presentation. Overall, it was a positive experience. One piece of advice is to make sure you do your research into CGG and the technology that they use before both interview stages.

Video interview covered topics like what you learned at univeristy, some basic maths and seismics questions. After passing it- Assesment Day in their office: face-to-face interview was based on previously sent information and covered some seismics fundamentals.
