Narrative:
ATC changed the arrival and issued a speed up followed by a slow down speed restriction and also a descent clearance somewhere in there. The PF inadvertently deleted the crossing altitude restriction at zzzzz. He selected vertical speed to continue the descent and I failed to ensure we changed the MCP altitude to prevent going below 17;000 feet. Subsequently; I verbally intervened just prior to descending below 17;000 feet; but didn't do so effectively. We descended to 16;750 feet before recovering to 17;000 feet.contributing factors included: day one of uoe [upgrade operating experience]. PF has been on an am schedule. Pm didn't sleep well the night prior. Pm lack of recent experience in first officer seat.I made the assumption that the PF was aware of the restriction and would meet it. When I noticed that the MCP altitude window was incorrect; I verbally intervened but did so ineffectively. I should have done a better job of bringing it to his attention and physically intervened as necessary.

Narrative: ATC changed the arrival and issued a speed up followed by a slow down speed restriction and also a descent clearance somewhere in there. The PF inadvertently deleted the crossing altitude restriction at ZZZZZ. He selected VERT SPEED to continue the descent and I failed to ensure we changed the MCP altitude to prevent going below 17;000 feet. Subsequently; I verbally intervened just prior to descending below 17;000 feet; but didn't do so effectively. We descended to 16;750 feet before recovering to 17;000 feet.Contributing factors included: Day one of UOE [Upgrade Operating Experience]. PF has been on an AM schedule. PM didn't sleep well the night prior. PM lack of recent experience in FO seat.I made the assumption that the PF was aware of the restriction and would meet it. When I noticed that the MCP altitude window was incorrect; I verbally intervened but did so ineffectively. I should have done a better job of bringing it to his attention and physically intervened as necessary.
