I applied for a position at Palantir and was invited to the Online Assessment (OA) stage.

The OA included LeetCode-style coding challenges, with an easy question involving creating a cipher program in Python and a medium-level question related to finding the path with minimum effort.

After completing the OA, although I wasn't able to proceed to the next steps in the interview process, the questions tested my problem-solving skills. I understand that if I proceed, I may face more technical interviews covering algorithmic problem-solving and system design.

I'll continue preparing to ensure I'm ready for the next stages.

The first question involved creating a simple cipher program in Python. The task was to decrypt an encrypted string by replacing each character with the Kth character in the counter-clockwise direction on the English letter wheel.

The second question required implementing a function called "efficient trek." The function took an array of trail lengths and the number of days to cover all trails. The goal was to return the minimum sum of the longest trail on each day, based on the specified conditions. The example provided was a scenario with six trails and a given record value, and the task was to calculate the minimum sum of the longest trails.
