It was 6 months Intern Offer. First Round: written test(1 hr) 2 coding questions. Questions were based on graphs(dfs) and Dijstra's algorithm with modifications. 1st Question: Number of Islands problem. 2nd Question: A student Ram wants to go to his house from college by bus. There are n cities numberes from 0 to n-1 and also there were n busses from each city to every other city every hour i.e. if a bus from city 0 starts at time t to city 1 then another bus at time (t+1) hr starts from city 0 to city 1. You have to find the minimum time in which Ram can reach his house. Ram boards at city 0 and his house is at city n-1. Input: number of cities and time taken for each bus to travel from each city to other. Output: minimum time. Around 18 were selected after this round. Second Round:(Debugging Round) - 20min 1 Question with erroneous code. Question: spiral order traversal of matrix. Speed was important i.e. solving in less time Around 9 were selected after this Round. Round Three : (telephonic interview with common editor) for around 1hr Questions were mostly on OS , Linux , OOPS concepts and 2 coding questions. coding questions were 1) Level Order Traversal of a tree 2) Two sorted matrices - matrix A with m elements and m+n size , matrix B with n elements and n size. Merge them in sorted order in matrix A. there was another round also. But me and my friend were selected after Round Three . From Round Four another one friend got selected.. Overall Process was very interesting.
