Here are some Google DS interview questions I got/some colleagues got during our Google DS interviews:
- How do you choose the number of resamples in bootstrapping?
- Give an example of a situation where you use mean and/or median.
- Explain overfitting.
- How do you evaluate the performance of a model?
- How do you solve an overfitting problem?
- Describe lasso to non-tech people.
- How does Lasso solve an overfitting problem?
These definitely aren’t the most challenging questions if you prepare for them ahead of time. Good luck to those who are interviewing soon!
