Experience:

This interview experience for an SDET intern role at Jupiter (a neo-banking app) was part of an on-campus placement drive. The process included a coding round and two interview rounds.

Coding Round:
The coding round comprised three questions. Two were LeetCode medium-level questions, which the candidate did not recall. The third question was "Parallel Sums": Given an array of integers, split it into two even sets such that both groups sum to the same number. If impossible, return -1. Otherwise, return a string representation of the first set (smallest first integer) followed by the second set, with elements sorted ascending and separated by commas. Example input:, expected output: 1,11,20,35,8,16,21,22. The candidate successfully solved this problem.

First Interview Round:
Questions asked in this round included:

• "Two Sum" problem (LeetCode) – find two numbers in an array that sum to a target.
• Explanation of solutions for "First Occurrence" and "Last Occurrence" problems.

Second Interview Round:
This round involved questions on matrix operations:

• Find the sum of elements on the "Primary Diagonal" and "Secondary Diagonal" of a matrix, requiring a program to be written.
• A problem related to generating a spiral matrix.

The candidate found these questions relatively easy and answered them confidently. Following the interviews, an offer letter was received.
