Infosys DSE Role interview questions

There were 3 coding questions and each was worth 100 points and the duration of the test was 3 hours. The test for the DSE role and Power Programmer role is the same. If you solve 2 or more questions then you have a chance of being qualified for the PP role, otherwise, if you are able to solve 1 question only then you will probably be shortlisted for DSE Role. I do not remember the exact questions but one was of Matrix, another question required String manipulation and the other ques was of Graph. I was able to solve only one question completely (100% test cases passed) and one other question only partially hence I was shortlisted for DSE Rol
