True but the latest Government statistics show that there are some 3 million without jobs (if you believe such a low figure) and only 40,000 vacancies registered. That imbalance has to he addressed before you can expect people like those interviewed (who seem to have had a rough deal anyway) to have any chance of getting any sort of work.
Additionally job centre staff, in the main, are only interested in ticking boxes ~ they don't actually try to find people work. The days when employers used to get a weekly call from their local job centre actively looking for vacancies have long gone ~ Yes they really used to do that and they used to follow up everyone they sent to an interview by calling the employer to ask why the person had been turned down and if the vacancy was still available for others to be sent along.
