Cashfree visited our campus in August 2022 for FTE for his or her Bangalore workplace. CGPA standards had been 6.5 and above.
There have been 5 rounds.
Spherical 1 (On-line Check – Hackerrank): It was a web-based examination that had MCQs associated to CS fundamentals and a pair of coding questions (I don’t bear in mind).
Round 16 folks had been chosen and I used to be one in all them.
Spherical 2: (Technical Interview – Hackerrank, 1 Hour): This was a DSA spherical, the interviewer greeted and launched himself and requested me to introduce myself. The interviewer pasted two questions in whole on the hackerrank platform (the interviewer and I share the identical display) and requested me to learn and perceive the query.
Query 1: Contemplate two arrays A and B the place every consists of n integers. In a single operation:
Choose two indices i and j (0 <= i, j < n) Swap integers A[i] and B[j] This operation could be carried out most okay instances.
Discover the utmost variety of distinct parts that may be achieved in array A after at most okay operations.
Query 2: Contemplate array A. The associated fee at an index is outlined because the variety of distinct parts which might be current in all the weather left to the index (together with the aspect on the index). The price of the entire array is outlined because the sum of prices in any respect indices.
Discover a permutation of the array A, which might give the minimal value of the array.
Instance:
A = [1, 2, 2, 1, 1, 3, 1, 3, 2] Value of A = 1 + 2 + 2 + 2 + 2 + 3 + 3 + 3 + 3 = 21 A doable permutation of A = [1, 1, 1, 1, 2, 2, 2, 3, 3] The associated fee for this is able to be 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 + 3 = 16, which might be the minimal doable value doable.

- Preserve the session interactive. Let the interviewer know what’s going on in your thoughts.
- I couldn’t get essentially the most optimum resolution for the primary query instantly, I mentioned the brute drive which had a time complexity of O(n^2), and coded it out for which 13/15 circumstances handed.
- As I used to be discussing my method with the interviewer, I received one other thought, mentioned it, and coded it out which had a time complexity of O(n).
- The entire take a look at circumstances handed and moved on to the second query.
- The second query was easy, organize the weather primarily based on the frequency in descending order.
- Lastly, the interviewer requested me If I had any questions, I requested him in regards to the firm, about his work, and requested for suggestions.
