Microsoft Summer Internship interview questions

Programming test online, 3 questions in 90 minutes. After more or less one month had a technical interview (not programming). Asked about experience, to tell about myself and what product do I know of the company and how would i improve it.

A coding test was sent via email at first, and after passing it, i got interviewed by 2 software engineers at microsoft as a live coding interview session. The first one asked about a dynamic programming problem while the other asked about a simple hashing problem
