Hi, your question is probably already answered but I thought I would chip in with my current experience. I applied to a job with my pre reg employer and was brutally interviewed for over an hour... seemed pointless as I literally knew the interviewer but still did it anyway. So far I've only heard of a few people get the job from 70 applicants (I have been offered one thankfully). So no, you are not guaranteed a job with the company you work!
