First round was hackerrank coding test consists of 3 problems (Greedy and Dynamic programming ) followed by 10 mcq. 2nd round was problem solving round where they asked 1) Write a code to find first and last index of a number in sorted Array ( expected time complexity O(log N) ) 2) Design and write a code for Network Request Analyzer . There will be a csv file consists of REST Api endpoint , response time, method type and all other data. I need to write complete code with good practices and OOP design which will return Average Response time, Max and Min latency for all the routes. Route also includes path variable and query parameter.
