I applied through other source. The process took 2 weeks. I interviewed at Microsoft (Madrid) in Sep 2021
Interview
Entrevista muy completa tanto en contenido técnico como en valores y habilidades.
Dos fases: la primera consiste en una elaboración de un case study con presentación de 10/15 minutos al team. Discusión del argumento y bastantes preguntas técnicas.
Entrevista con el manager y/o project manager con presentación y evaluación de aspectos más humanos y de experiencia.
Interview questions [2]
Question 1
¿Te has encontrado con un problema de inclusión social en ambiente laboral? (explicación, solución)
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.
