Paul Pritchard just trained me up and did a good job too! Also Mark Brocklehurst trains in Chester too.
When I got the job in August I did SCAAT, then an assessment workshop which basically was a group exercise to describe the perfect conductor, don't be too loud or too clever, be respectful, but also be confident etc, followed by interview with a conductor manager or 2. After being offered the job I had a medical involving colour vision, hearing bleep test, drug and alcohol testing and lots of questions regarding medical history. On passing the medical they sent my contract and my trainer sent a training timetable to give us some idea of what it would entail. From application to start of training took approx 2 and a half months, very quick turnaround! Good luck!
