Narrative:
Departing lax on the ladyj 4 SID; I was the first officer; PF (first officer; pilot flying). As a relatively new first officer; I was unfamiliar with lax. Due to time constraints from an unscheduled aircraft swap; the captain rushed through the briefing and did not give me an opportunity to brief the departure. I interjected to discuss a separate issue with the departure; an 'at or below' versus MCP selected altitude; which was resolved; but I did not adequately brief the entire procedure to include the 'maintain 250 until advised' note. This constraint was not in the FMC.climbing through 13;000 feet; (cmd B engaged); ATC queried our speed; which was 305 KIAS. As the captain/pm (pilot monitoring) responded to the query; he simultaneously selected lvl chg on the MCP and yanked back on the thrust levers. I was immediately confused as to who was flying the aircraft; if he was taking the aircraft or if I was still flying. I did not understand why he did not ask or direct me to make the change as PF. The situation was resolved and we continued to [our destination] uneventfully.an adequate departure briefing is mandatory. As the first officer; I should have been more assertive in requiring us to slow down and properly brief the procedure. This would have eliminated the speed error after departure. To mitigate confusion during flight; I believe positive exchange of flight controls should always be used. Any time saved in correcting this speed error by the captain manipulating the MCP was; I believe; negligible.
