resume question

I don't know where you can obtain resume books for schools.

As for the bias against the words "responsibilities include" is because it's wasted words. The business school resume should be accomplishment focused. Leading, creating, initiating, reducing, increasing, managing etc. If you want to have at least one bullet stating your job responsibilities that's fine too. However, you can just state them without wasting words on "responsible for" or something like that. If you're responsible for being a liason between two departments then simply say, "Liason between marketing and finance departments for $200MM product lines including technology and services" or something like that. Even better if you could say something like "Foster collaboration between..." Think of the resume as your greatest hits page. You can use the employment portion of the application to delve more into your duties and responsibilities.
