Hi I've recently completed a RTT course. It too was a joint course but part time (I'm primary). The interview itself was very informal. Can't really remember the questions I was asked but think they really just wanted to check my commitment to return to teaching so I was asked why I wanted to return, what I hoped to gain from a RTT course and also questions about what I think my strengths and weaknesses would be back in the classroom. I was offered a place there and then. I think the course was really beneficial for me. I really lacked confidence in teacher (my last year in teacher had been horrible!) and my self-esteem was at zero. The course was great for allowing me to build up my confidence through the school placement. It was also really good for interview tips, applying for jobs, etc. I applied for 2 jobs and was interviewed for both. I got the 2nd job! When HT have asked me how long I'd been out (5.5 years) they always say 'That's not that long'. But I think HTs like the fact I've completed a RTT course because it shows commitment to returning to the profession. I know a few others on the course have also got jobs but many others are joining supply agencies. I don't think I would have got a job at all, and certainly not so soon, had I not completed the RTT course. Hope that helps and good luck with your return!
