Renault Group interview questions

Good experience, talking to really nice people who made the interview easier to do. Had to complete a presentation for the final assessment. After spending a lot of time preparing, after completing the final stage, they haven't even got in touch 4 weeks later saying whether I was successful or with any feedback. Would be understandable if this was just ignoring an application, but at this point I have sent an application, had a phone interview, done psychometric tests, and a presentation on the final stage. Very disappointed.
