The phone screen was straightforward, starting with some basic algorithm questions. After a few minutes of discussing my background, we dove into a coding challenge about finding two numbers that sum to a target. I enjoyed explaining both the brute-force method and the optimized hash map approach. The wild part was that I had practiced a similar problem on PracHub just a few days earlier, so it felt familiar. Following this, there was a technical round focused on machine learning concepts, which went smoothly before I received a written offer. Overall, a positive and engaging experience.

Question 1
Given an array of integers, find two numbers that sum to a target value. Start with a brute-force O(n^2) approach, then optimize using a hash map to O(n). Walk through edge cases (duplicates, negative numbers, no valid pair) and discuss the space-time tradeoff.
The interview process was smooth, and the interviewer was professional and friendly. It was online and took about 35 minutes. The recruiter will give you some guidelines on how to prepare.
