Round 1 - 1:1 interview with a Training and Recruitment Manager. Questions were general behavioral type (Tell me about yourself, previous internships, final year project etc.). Straightforward and took about 30 min. Round 2 - Full day session. First, was a group activity (build a paper tower). Next was a 5 minute impromptu verbal presentation to all the managers and the other candidates. Topic was "Most successful project you have done". Lastly, there was a interview session with 3 managers. Questions were a mix of behavioral and technical. Eg. Strengths, weaknesses, basic questions on mechanics. I think the focus was on how you think through the question. Received an offer within a week and accepted.
