    Coding and SQL questions came up early in my microsoft data science interview. Here is an example I faced:

    Microsoft Data Science Interview Machine Learning and Case Studies

    Machine learning and case study questions made up a big part of my microsoft data science interview. The interviewers wanted to know how I approached open-ended problems and built models for real scenarios. Here are some questions I tackled:

    • How do we deal with missing data to construct a housing price prediction model?

    • How would we build a bank fraud detection model with a text messaging service?

    • Given a dataset with keywords and their bid prices, how would you build a model to bid on a new unseen keyword?

    • How would you know if you have enough data to create an accurate enough model?

    • Imagine you work as a data scientist at Amazon. You want to improve the search results for product search but cannot change the underlying logic in the search algorithm. What methods could you use to increase recall?

    • How would you design a model to detect potential bombs at a border crossing?

    For each case, I broke down the problem with the interviewer. I started by exploring the problem, identifying edge cases, and thinking about what mattered most for the business. I defined success metrics, looked at available data, and suggested new sources if needed. I picked features, decided how to label the data, and chose a model that fit the problem. I talked about how I would validate the model offline and measure its performance. I also explained how I would deploy the model and monitor it in production.

    Note: The interviewers wanted to see my problem-solving process, not just the final answer. They asked follow-up questions to test my understanding of metrics, data sources, and deployment strategies.

    These questions tested my ability to think critically, communicate my approach, and connect technical solutions to business impact.

    Microsoft Data Science Interview Behavioral and Teamwork Questions

    Behavioral and teamwork questions showed up in every round of my microsoft data science interview. The interviewers wanted to know how I worked with others, handled challenges, and learned from experience. Here are some questions I remember:

    • Write a SQL query to find duplicate records in a table.

    • Explain how you would handle missing data in a dataset.

    • Describe a project where you used data to solve a business problem.

    • How would you assess the results of an A/B test?

    • Debug a slow SQL query and suggest improvements.

    • Build a predictive model for a real-world scenario, like customer churn or fraud detection.

    These questions often focus on practical skills. Interviewers want to see how you approach real business problems, not just textbook answers.

    Trends in Recent Interviews

    I noticed some clear trends in Microsoft data science interviews over the past two years:

    • Interviewers put a big emphasis on the basics: statistics, data querying, programming, and machine learning.

    • The competition has increased, so candidates need to show strong skills in these areas.

    • Many candidates shared that they faced questions about both technical topics and business thinking.

    Tip: If you want to stand out, make sure you can explain your thought process clearly and connect your answers to business impact.

    Comparing My Experience

    My own interview experience matched some of these patterns, but I also saw a few differences. I had several technical rounds that focused on machine learning, natural language processing, and data structures. Some of my peers, especially those interviewing for data analyst roles, got more questions about SQL, data visualization, and business acumen.
