Microsoft Internship, Software Developer interview questions

1CV 2Screening 3 Final round Made it to the last round. They also asked open questions about implementation of different ideas. Messed it up with an easy question about prefixes in a string sequence.

2 back-to-back interviews with the introduction at the beginning of the interviews. Was having Behavior Questions and Technical Questions in the first interview but full Technical Questions in the second one. The difficulties were based on the courses that had been taken in college. I was having questions on medium difficulties of sliding windows and binary search questions.
