Here’s what we’re going to do, first, I will present you with a list of common data science interview questions and then I’ll tell you how to prepare for them. I watched multiple YouTube videos and reels to generate an entirely new perspective on interviews, and that’ll keep the anxiety away—where it should be. I asked ChatGPT to search data analyst and data scientist job descriptions separately on both LinkedIn and Indeed, and based on their JD, what questions may be asked by the interviewer. This is the list it presented me with, you can ignore reading them and skip to the title “Being the Lead Actor in your Movie”:

Data Analyst Interview Questions:

  • Describe your most complex data project from start to finish. What were the most difficult challenges, and how did you handle them?
  • What are the best practices in data cleansing?
  • How do you handle missing or corrupted data in a dataset?
  • What data analysis tools do you have experience with?
