Microsoft PhD Data Science Intern interview questions

I recently got accepted by Microsoft for a Data Scientist PhD Internship for Summer 2026 in Redmond, Washington. I applied for the position on August 16th and received the online assessment on August 19th. Based on my performance in the OA, I was shortlisted for the final round of interviews, which all took place on the same day. There were three interviews, each lasting 45–60 minutes, with a 15-minute break in between. Interview 1: Machine Learning breadth interview covering core ML fundamentals and concepts. Interview 2: Coding question followed by a system design question. Interview 3: A project manager asked about the role of ML in customer-facing products, its nuances, and some resume-based questions. I received my final offer on October 7th. Still wrapping my head around it, to be honest. It was an intense but thrilling experience from start to finish. Happy to share more details or answer any questions about the process.
