Applied online. Was offered a telephone interview, which lasted around 30 minutes, followed by a final-stage interview at their offices in Crawley which lasted about 3 hours. The final-stage interview consisted of an initial interview with HR and covered the usual questions... why CGG?, give examples of leadership style and team-working, etc. etc. This was followed by a technical interview which was quite in-depth, and focused on reflection events, velocities, and multiple identification (e.g. seabed/interbed/peg-leg multiples).

2 session and quite tough thou. 1st one got me only 10 minutes to get it done. 2nd one made me a little nervous as it involves few technical questions.
