McKesson Revenue Recognition

Hello everybody,

Tomorrow I have a phone interview with McKesson for a Revenue Recognition type of role. I pasted the job description below and noticed they want strong accounting knowledge of revenue recognition. I studied Finance and Economics and have decent knowledge of the accounting cycle. This past year I've worked at a large corporation as a Financial Analyst on the FP&A team, but not sure how my experience will qualify for this role.

Does anybody have a link to a website with an overview of this type of accounting?
Does anybody have any idea of the type of questions they might ask me?

"You are interviewing for the Finance/Accounting Specialist Role.
