Interviewers will expect financial analyst candidates to be well-versed in financial markets, modeling, and analysis. Make sure you are comfortable with both micro and macroeconomics. In addition to highly technical questions, be ready to answer a few behavioral questions that will show off your communication and collaboration skills.
Pretend 1% of the population has a disease. You have a test that determines if you have that disease, but it's only 80% accurate and 20% of the time you get a false positive, how likely is it you have the disease.
divide by reciprocal, multiply by .8% = 1%
 Fact: 1% of the population has the disease (given)  Data: Test is only 80% accurate, and 20% inaccuarate (given): Assume, Population = 10,000 people 1% have the disease = 100 people 99% do not have the disease = 9,900 people Of the 1% who have the disease 80% tested +ve = 80 Of the 99% who don't have the disease 20 tested +ve = 1980  Question: How likely is it that you have the disease? To identify that you have the disease you have to test +ve and actually have the disease = 80 / (80+1980) = 80 / 2060 = 3.88%
