Applied through career center and got a response within a week. Phone interview happened the following week. Interviewer appeared to be tired and a bit disinterested (But it may be my perception )
Interview questions [2]
Question 1
Of all the questions he could ask, he picked the following ones (although to be fair to the interviewer, he can ask any thing he wants since it is an interview)
I) Generate a fair coin from a biased one. II) Generate 7 integers with equal probability from a function which returns 1/0 with probability p and (1-p). These were not worded this way, but essentially this was question.
Tell me about your most recent project. When I proceeded to describe it, he asked me several questions, including how you think you will improve your model given that you have 6 more months etc.
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%.
Phone screen with HR/recruiter. Less than 10 mins. Very basic mostly about role fit and my background and resume. Did not hear back from them at all. Very unenthusiastic during the call
I applied online. I interviewed at Microsoft (Hyderābād) in Feb 2026
Interview
Overall 3 rounds with 2 technical and 1 managerial. The 1st round was DS and ML heavy with some analytics. The 2 nd round was resume, SQL and causal /AB experimentation. The managerial round was resume related and some behavioural questions.
