Add your answer

Initially first was HackerRank assessment then first round was of DSA. Asked 3 questions
1) Find max sum of substrings of length k
2) Find whether 2 strings are anagram or not
3) There is a Array and Find the max sum of subsequence. If you take element index at 1 in array then you are not suppose to take element index at 0 & 2 -> I solved it with Recursion then applied DP.

Cracked Round 1.

This was a machine coding round where I have to create 3 API of Cricbuzz feature.
1) Post API which will take Match Details and we have to create points table like we have in IPL
2) Get API to fetch Point table based on total Points
3) Get API to fetch last 3 matchs of a team and there results.

This was Code review round. Interviewer first asked about my project in my current company and multiple questions like hiw many team member and how many juniors u are handling. Then we move to code review and he checked extensibility of code by asking if I have to add year wise point table then How will you add then If there are many Tournament then how you will implement.
