I had my first round of interviews at the Wood Mac office. Went directly from application to face-to-face interview. Met with consulting team members and had an interview followed by a written assessment.
Asked questions about qualities of successful consultants, why you would make a good candidate, etc. Also asked a lot of questions regarding the energy industry. Issues, future predictions, process, etc.
Be up to date about key issues in the industry. Also should know what has happened in the last few years, and also any future predictions.
