My interview was quite long (1 hour and 15 minutes). It was almost completely technical, related to many mechanical concepts that we have learnt in engineering. They also tested a little on algorithms, mathematics and codings, to test me for the suitability for a new project. From the written test, the answers that went wrong in the technical paper were also discussed. Many questions were put to me from various subjects, also there was a board in the room upon which a few questions and diagrams were discussed. The interviewers were very friendly and knowledgeable too. It was a good, rigourous testing.
