There’s nothing more frustrating than failing interviews.
And one of the most common complaints is “insufficient knowledge in answering math questions.”

Well, I’m here to tell you that if you are explaining math in a data science interview...
... then you are falling for a massive trap.
Why?
... then you are falling for a massive trap.
Why?
Explaining math in an interview is:
1. Not productive.
2. Easy to mess up
3. Likely to be criticized
So what's the solution?

So what's the solution?
Use this 3-step framework for answering “math questions”:
Example: K-means algorithm
Example: K-means algorithm
1. State why the math concept is important
Clustering with the K-means algorithm is important because it can help us identify similar patterns from groups in our data.

2. Refocus on the business
K-means can help the business identify similar customers based on their purchasing habits.

3. Show how you’ve used it.
I’ve used K-means to identify similar customers and also to show outliers that are totally unrelated to others but are unique and important to the business.
This helped me do XYZ.

This 3-step pattern can be used for ANY math, statistics, or data science concept in the interview.
It works by totally avoiding the “nuts and bolts” of the math.
Most importantly, it showcases YOU and your experience in using the tool to help the business.
