Hi -I have an interview soon for an on track plant specialist post within NetworkRail. Im Ok about the interview as I confident about my competencies but the invitation mentions a 30 min test - written, numerical, scenario and technical. Im guessing the tests will be SHL tests but normally these are 30 mins each and I have just clarified from the recruitment support service that it is a 30 min test in total. Does anyone have experience of this test so I know what to expect and can do some preparatory work ? many thanks in anticipation
