From my day (January the 19th), only one was called for a TR beginning in May.
We were 16 at the end of the day. 8 for the Sim.

From my sim assessment day (January the 30th), we were 3 (from the 17,18 and 19 interview days). One was called around 5 days after the sim for a TR beginning in May.
So I'm still waiting
