Vicky…I would suggest going back to your CFA books and trying to recreate examples in Excel, work them out. What these guys say is true, if you passed level 2 you should know the answer to the questions you posed and after research you should ask…it is something critical employers will look for, your initiative and ability to research.
Also, curious, what do you mean by Financial Analyst/Equity Research profile? Sounds like they don’t know what they are recruiting for.
