60 minutes Correlation One MCQ:

It has many questions which are extremely subjective, and that is what is really frustrating.

Some questions are just poorly worded.

Gave interview some time last month. Not sure of the outcome.

Three questions were extremely subjective. It was very frustrating. The rest of the questions are fairly okay/easy. Some MCQ questions were:

• What would be the accuracy of a Logistic Regression model trying to separate a circle?
• Which of the specific points are unlikely to come from a specific normal distribution, given its mean and covariance matrix?
• Subjective question on Heteroskedasticity.
• Subjective question on A/B testing (Would the number of false positives increase or decrease?).
• Mean of Pareto Distribution in Central Limit Theorem.
• Find P(3X + 4Y) > 5 given mean and variance of X and Y that are IIDs.
