Formal Interview with panel of 2 people. This is a imaginary context. This can be treated as a test post. I will create a proper post later when it make sense to me.
Feeling thrilled to have accepted the offer, I look back on this interview process as both challenging and rewarding. It began with a technical round where I tackled a complex A/B testing design question, followed by a SQL query on user retention. The final stages included a system design discussion that had me sweating, but honestly, the system design section on PracHub prepared me well. Each step pushed my limits, but the culmination was definitely worth it, landing me a role at Microsoft.

Question 1
Design an A/B test to measure the impact of a new ranking change in Bing, and explain how you would handle network interference between treatment and control users.
Write a SQL query that computes 7-day rolling user retention from a daily events table, then flags cohorts whose week-over-week retention dropped more than 10%.
The hiring process consists of a HackerRank home exam, followed by three technical interviews covering LeetCode-style problems and system architecture. Once this is done, you will have a final HR interview.
