This page represents a list of **questions** which can be used for preparation of **machine learning interviews**. Here is the link to first set of machine learning interview questions as part of this series. The following are some of the areas covered in this set of questions:

- Univariate vs Multivariate linear regression
- Supervised vs unsupervised learning
- Algorithms such as KNN, K-means, SVM etc.
