Very good interview, The interviewers made me feel very comfortable.The panel generally contains either your 'to be' line manager and HR representative OR line manager and a lead engineer + HR. My interview was divided into two parts first part was technical and second part was scenario based. I dont work for Invensys anymore and they are acquired by Schneider but I would recommend it to everyone who is looking for good personal development and challenges. The interviewer is not only looking for "what can you do" but also "How will you do it"
