This is an example of a technical question. As a data scientist interviewing with Uber, you can anticipate that most of the questions you will be asked during a job interview will be technical.

"One of the key steps I take to ensure that the regression model fits the data is employing the R-squared methodology. This addresses the relative measure of fit. Another is to use the F1 score to evaluate the null hypothesis. One last methodology is a root-mean-square error, or RMSE, which provides the absolute measure of fit."
