Round 1 - HR 

(1 Question)

Round duration - 90 Minutes
Round difficulty - Medium

This round happened on the same day as JAM in the afternoon time. A slot of 20 minutes with respective timing was already sent to the selected students. Interview can’t be generalize as anything can happen over there and hence this was exclusively my experience. 
To have a quick judgement about the person, I believe nothing is better than throwing before him/her some puzzles (mathematical/ analytical/ programming problems) and see the approach. I received back-to-back 4 problems after a quick and brief introduction. The coding problems I got were way too easy (just basics: searching & mathematical). The harder part of this round was the puzzles (tricky, mathematical, related to probability). At last, I was asked a question on DBMS and the interviewer asked if I know JAVA.

  • Q1.

  • Ans. 

    Search for a number in a sorted array and determine its existence for multiple queries.

    • Use binary search algorithm to efficiently search for each query integer in the sorted array.

    • For each query integer 'X', check if it exists in the array 'A' and output 1 if found, 0 otherwise.

    • Ensure the array 'A' is sorted in non-decreasing order to apply binary search effectively.
