SAM Junior Engineer Interview Questions and Answers

There were 2 DSA questions that we had to solve on HackerRank. One of them was a medium dynamic programming question - minimum insertions required to make a string palindrome. The other was a fairly easy question that required knowledge of permutations and combinations. We just had to figure out a maths formula given the situation.
1st round also involved a logical game that we had to play. We were scored based on coding + game and shortlisted for next round.

An interviewer joined me on zoom meet and sent a HackerRank link to a question. It was a medium dynamic programming/backtracking question. I solved it but only half the test cases ran while others threw TLE as my recursive code took exponential time.
