Topics Asked: Array manipulation, finding kth permutation of a string, ways a number can be expressed as a sum of more than 1 consecutive natural numbers, projects, polymorphism, virtual functions, OOPS concepts, stock trading problem (buy/sell stocks to maximize profit), Data Structures & Algorithms, Operating Systems, Database Systems, SQL, Networks, Quantitative Aptitude, Problem-solving, Logical & Verbal Reasoning

Experience:

The application was made through the company's careers page, followed by an invitation for an Off-Campus test.

The HackerRank Test was 90 minutes for 100 marks and included a Programming Section (2 coding questions, 20 and 40 marks, 50 minutes) and an MCQ Section (10 technical, 10 aptitude questions, 20 minutes each, negative marking). The first coding question was easy, related to array manipulation. The second was about finding the kth permutation of a string. Technical MCQs covered Data Structures & Algorithms, Operating Systems, Database Systems, SQL, and Networks. Aptitude MCQs covered Quantitative Aptitude, Problem-solving, and Logical & Verbal Reasoning.

In the CodePair Round (Technical Interview 1), two programming questions were asked. The first was easy: find the number of ways a given number can be expressed as a sum of more than 1 consecutive natural numbers. The second question involved a stock trading problem: given stock prices for N days, buy or sell to maximize profit. There was also a discussion on projects and questions related to polymorphism, virtual functions, and other OOPS concepts.

The second Technical Interview was also on HackerRank CodePair. The candidate was asked to solve one programming question which involved a stock trading scenario.
