Round 1: There was an online coding test consists of 2 questions. First question was to check a number is Fibonacci number or not. Second question was to convert decimal integer to roman.
Round 2: First Technical Round: In this I was asked about basic of data structure and algorithm. Then interviewer asked to write code for DFS (https://www.geeksforgeeks.org/depth-first-search-or-dfs-for-a-graph/amp/). After that he asked to find the shortest distance from source to destination in a graph and write pseudo code for it(https://www.geeksforgeeks.org/greedy-algorithms-set-6-dijkstras-shortest-path-algorithm/). Then he asked to find the number of set bit in binary representation of a integer(https://www.geeksforgeeks.org/count-set-bits-in-an-integer/amp/).
Round 3: Second Technical Round: in this I was asked about quick sort, its code, complexity and how to decide pivot element(https://www.geeksforgeeks.org/quick-sort/amp/). He asked one more question which I don’t remember.
Round 4:It was HR round. HR asked about why do you want to join this company. What are your weakness and strength and some other behavioural questions.
