Experience:

This candidate interviewed for a Software Engineer II role at LG Ad Solutions, formerly Alphonso. The application was submitted through a referral. The interview process consisted of two technical rounds, with a third High-Level Design (HLD) round not occurring as the candidate did not clear the initial rounds.

Technical Interview 1: This round focused on Data Structures and Algorithms (DSA), Low-Level Design (LLD), resume-based questions, and discussions related to the candidate's current projects. Specific coding problems discussed were:

• "Remove K Digits" (LeetCode problem): The candidate discussed a brute-force approach but was unable to optimize it.
• "Find Bottom Left Tree Value" (LeetCode problem): The candidate solved this problem optimally.

Technical Interview 2: This round involved a Low-Level Design (LLD) problem. The candidate was asked to design a shopping cart system that supported various discount coupons at both item and cart levels. The candidate reported that this round went quite well, and they were able to present a good design on the whiteboard.

Final Thoughts: The candidate described the overall experience as a good learning opportunity, and the interviewers were noted to be quite nice.
