Microsoft Internship, Software Developer interview questions

I applied in August and get an email for the final round of interviews in November. There were no other rounds before this final one. The final round consisted of two interview, each with a coding question followed by behavioral questions.

The first round had 2 coding questions. Lot of hidden test cases were there. Time limit was 140 minutes. The questions can be expected from dynamic programming or greedy. Speed and accuracy also matters.
