Wayfair Machine Learning Engineer interview questions

It was a long test with very less time for answering the questions. Answers should be right on top your head. One of the Speed Coding question was to find the minimum amount of power that Gandalf should carry so that when he fights with many minions and reaches the boss, he should at least have power = 1.

3 questions were extremely subjective.. It was very frustrating. The rest of the questions are farely okay/easy. Some MCQ questions were 1. What would be the accuracy of a Logistic Regression model trying to seperate a circle. 2. Which of the specific points are unlikely to come from a specific normal distribution, given its mean and covariance matrix 3. Subjective question on Heteroskedasticity 4. Subjective question on A/B testing (Would the number of false positives increase or decrease) 5. Mean of Pareto Distribution in Central Limit Theorem 6. Find P(3X + 4Y) > 5 given mean and variance of X and Y that are IIDs
