This info is a few years ago now but:
Essentially an interview with HR, Mgt and Fleet Mage/Chief Pilot on Q400 at HQ Exeter. Then to Woodford for BAE 146 SIM ride - std stuff - basic instrument pattern work.
They were offering around £24k FO with £18k bond (3 yr) at the time. Fast Track commands were offered to those with over 1500h Turbine but still had to start on FO terms.
