There were 2 problems in OA of De Shaw for SMT Position. I solved both of them using dynamic programming. Both of them seemed Medium to Hard. Total time alloted was 90 minutes.

I was able to pass all 15 test cases of first problem but for the second one, I was only able to pass 13 out of 15 test cases. 2 hidden test cases were giving wrong answers.

What are the chances that I will get an interview call? Is it only if both problems will be completely solved or even 1 fully and 1 partially will be sufficient?
