Anyone get an approved L-1B?

[IAmTheRainKing 3]

My girlfriend is going for her L-1B interview soon. She works for a large global organization that has blanket L-1s She's based in Europe and the lawyers that her company use for the transfer process typically work with employees that are specialized in coding. My GF is being transferred so she can bring her specialized marketing skills and experience to the North American markets. There are a lot of skills she brings  that the lawyers just don't understand because they're not marketers, including specialized knowledge and internal tools that she not only has expertise on, but will be responsible in teaching other's in the USA market.

 

Does anyone that had an approved L-1B have any tips on how she can ace the interview? Does the fact that it's an L-1B under blanket license put her under less scrutiny? She's afraid that because the lawyers don't understand how her marketing skills and trainings are just as important and specialized as the coding skills they are used to dealing with, she might not be setup for as much success as other more technical employees.
