As written in the title I did an internship with Microsoft India in summer of '22 and got the PPO.
Number of rounds : 3(Presentation, Technical, AA(As Appropriate))
Presentation: This is a mandatory round for all the interns where we have to present in our project and journey in front of all the org. members including M2 and sometimes M3 as well. Few technical questions regarding project were asked from each interns.
Technical round: I had one technical round(there can be more or even none) where I was asked 4 dsa questions along with few SQL and API related questions as well as OOPS in C# and some general technical questions and project discussion. The round lasted for about 2 hours. A side note: The questions and expiriences in this round are highly dependent on the interviewer.
As Appropriate(AA) round: This round was quite short and the focus was mostly on hr questions along with very few and rapid fire type of questions on the technologies I had worked with during my internship. Other than that only the approach of 1 dsa question was asked.
Final verdict: PPO offered. :)
