The Doordash interviewer is asking a technical question, which requires you to compare different visual models used to analyze data. Knowing the differences between two similar but different techniques used to illustrate the results of data analysis will confirm that you are qualified for this role. Technical questions like this are best answered by comparing the terms presented by the interviewer and possibly providing an example of how they are used in your profession. Your answer should also be brief and to the point to provide the Doordash interviewer the opportunity to ask a follow-up question.

"Boxplots and histograms are both visualizations used to illustrate a data distribution that communicates information in different ways. Histograms are bar charts that illustrate the frequency of a numerical variable's values. I use this to understand the shape of the distribution, the variation, and any potential outliers that may skew the data. While boxplots don't illustrate the shape of the distribution, they enable you to view information such as the quartiles, the range, and outliers. I believe boxplots are more useful than histograms when comparing multiple charts."
