First round was a phone interview, mainly about the resume ,and asked some questions about l1 norm and l2 norm. Second round was a on-site interview. There were 4 back to back algorithm interviews.

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.
