You should be intimately familiar with the traditional cuisine of several European countries. You should also learn to bake pastries and prepare snacks. Being knowledgeable of wines can help, depending on household.
You should adapt to a strict schedule of keeping places clean. No amount of mess can wait until tomorrow. You should also learn the professional methods for cleaning, for example having a dedicated cleaning set and procedure for bodily fluids separate from other spills. These are industry standards and might be mandated by law. You might want to take a clearing course to learn these properly.
Your master's study is an exception to this. They might not find it pleasant if you've cleaned their half-done projects away. Ask the master how and then it's okay to clean there.
You should also prepare to wash and cloth your master, as well as to satisfy their bodily desires.
You're likely to need to adapt your sleep cycle to service work. The master's breakfast and bath should be ready when they wake up or return home (and so should be you). Even after your master goes to sleep your work is likely not at its end, you'll be preparing things for the next day. You might want to test your stamina by seeing how many days you can go on minimal sleep and food.
In case you find yourself working as a head maid with multiple underlings, or as an underling, you should have decent people coordination skills. You'll want to learn to control your jealousy too, if another maid is more popular with the master.
But most importantly, you should have a submissive personally. You're going to have a bad time if you're not prepared to like being entirely at the mercy of your master's whims.
It's also a plus if you have entertainment skills, such as being able to play instruments like the violin or piano, being good at video games or having good taste in anime.
