Every business collects data, and it's the job of the data analyst to analyze, interpret, and communicate that information in a way that will help drive company decisions. Employers will be looking for candidates with strong technical skills as well as a knack for conveying data in an easy to understand way. Expect a fair number of technical questions, which may include an analytical case study and a math brainteaser.
Case interview: basic business problem (if product X costs Capital One $4.00 per unit, with a $800 sunk cost, and we charge X amount of dollars along with a $10 annual fee, how many do we need to sell to break even, etc). Followed by a longer discussion of more complex problems that the situation might entail.
Mostly algebra, basic economics, and common sense.
total cost= 4x + 800 total income= x^2 + 10x to break even: 4x + 800 = x^2 + 10x solving for x by evaluating the quadratic equation above, x ~= 25.45 To break even, 26 units must be sold
Why is x^2?
