Not my own roster, but a random example of the most junior of the most junior fleet on a blind lines:
2 on 2 off, 4 on 3off, 3 on 1 off, 1 on 2off, 5 on 2 off, 4 on 1 off.
Mostly trips and mostly early starts, though this is isn't an indication of what a junior person can expect as it varies hugely. You can however expect to be working most, if not all weekends at the moment as a junior P2.
