1st Round Details: Technical and Aptitude test on Hackerearth platform ➢ Section 1: 40 questions based on programming concepts like operating system, object oriented programming, DBMS, and others. Remaining questions were general aptitude and reasoning based. ➢ Section 2: Two programming questions (Any language)
❖ You are given two strings S1
and S2
. You need to convert the string S1
into a palindromic string such that it contains the string S2
as its substring by using minimum number of operations. You are allowed to use only one type of operation i.e., you can replace any character of the string S1
with any other character.
❖ You are given a number n, you need to find all possible ways of positioning the numbers (n inclusive) such that the prime numbers till n occupy prime positions.
Further Process Details: ➢ Round 2 : ( Technical interview ): ❖ Started off with the basic introduction and discussed about the internships, skills, courses, projects and other hobbies. ❖ Questions on core OOPS concepts and java ❖ Questions on java 8 features, templates, lambda function and other functions. ❖ Discussions on linked list and was told to write pseudocode for iterative and recursive element search in linked lists ❖ Two programming questions given on spot to solve(java specific) : ➔ Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining. (Water trapping problem) ➔ Given a list of words and length L.Format the words so that each line will have only L character and fully justified (left and right justified).
➢ Round 3: (Directorial interview): ❖ Started off with the basic introduction and discussed about the internships, skills, courses, projects and other hobbies. ❖ I was told to write code snippet for one of the projects mentioned in my resume ❖ Questions on how java is different from C++ ❖ Questions on basics of java ❖ Questions on Strengths, weaknesses, interests and others.
➢ Round 4: (HR interview): ❖ Started off with the basic introduction and discussed about the internships, skills, courses, projects and other hobbies.
