It was an **onsite** process, rated **Moderate** difficulty, and ended in a **Rejected** result. The experience was submitted 9 days before the page observation on 2026-11-05; the interview took place about a month before that observation and lasted **1 day**. ## Interview process The process took under two weeks: 1. A recruiter made initial contact. 2. The candidate completed a **30-minute introductory call**. 3. Within a day, the candidate was invited to a **45-minute technical Zoom interview** with a backend engineer. 4. A decision arrived a few days later. The technical round combined three areas within 45 minutes: - **System design:** About 20 minutes on “what happens when you click Like on Spotify,” followed by data modeling for users, songs, and their relationship. - **Live coding:** Find the first duplicate in an array. - **Behavioral questions:** A time the candidate received feedback and the challenges of moving from a large company to a startup. ### What went well - Scheduling and communication were smooth. - The recruiter promptly answered a question about the interview format. - The interviewer was friendly and collaborative. - The design discussion was conversational rather than quiz-like. - The candidate clarified use cases first, described an event-driven design with Kafka fan-out, and discussed storage trade-offs. - The candidate solved the coding problem with an optimal **O(n)** approach after confirming the plan with the interviewer. ### What did not go well - The recruiter described the coding portion as practical rather than LeetCode-style, but the actual problem was a classic algorithm question, so the preparation guidance did not match the round. - Combining design, coding, and behavioral topics in 45 minutes made every section feel rushed and left little time for depth. - The candidate’s behavioral answer about receiving feedback was less structured than intended. - The rejection email was templated and cited a “different technical profile,” without specific feedback, making it difficult to identify areas for improvement. ## Interview rounds The experience lists **2 questions across 1 round**. ### Phone interview The listed round is a **Phone interview**. The specific questions were: 1. [What happens when you press "like" on Spotify?](https://www.aced.io/questions/7442) 2. Given an array of integers, find the first duplicate.

The team appeared to value structured thinking over polish, and interviewers left time for questions at the end. ## About Aced We are Aced, formerly Exponent.
