FAA CPL Multi Initial is a fairly easy checkride but the oral covers both multi questions and commercial questions, so the oral is harder. The flight portion is a cross country to start with and then you do Multi maneuvers such as vmc demo, se approach, engine re start in-flight, as well as steep turns, slow flight etc. But what makes it different (and easier) from the SE CPL is that there is no power off 180 or any other commercial maneuvers such as chandelles, lazy 8's etc.
The other thing is doing it this way, all commercial requirements must be met in the multi engine, that's why not all schools offer it as an option. But if you have no use in the single engine commercial, I would advise anyone just do a multi commercial.
