Initially contacted by an agency. Interview was arranged in Liverpool (HQ) though the job was in Newbury (just outside London). The people were really nice and the interview went smoothly. They asked to prepare a presentation of my choice which I chose as my final year project. They asked a few questions about my university/work experience (the standard stuff). It was very chilled as opposed to being grilled. The interview was with 3 people and it was more of a flowing conversation between us. The job had lots of travel involved so they ask questions about drivers licence/passports etc.
