We provide interview-preparation courses, questions, interview experiences, practice, and coaching through Aced (formerly Exponent). This question is listed under **Product Design** and **System Design**, and is associated with the **Software Engineer** role and **7AI**. ## Interview experiences **1 shared experience** ### 7AI — Software Engineer · Senior / L5 [Read the full interview experience](https://www.aced.io/experiences/7ai-senior-software-engineer-interview-7c441d) The candidate reported that the process took under two weeks. A recruiter first scheduled a 30-minute introductory call; within a day, the candidate received an invitation to a 45-minute technical Zoom interview with a backend engineer. The candidate heard the decision a few days later. The 45-minute technical round included: 1. About 20 minutes of system design: “what happens when you click Like on Spotify,” followed by data modeling involving users, songs, and their relationship. 2. A short live-coding problem: find the first duplicate in an array. 3. Behavioral questions about receiving feedback and moving from a large company to a startup. The candidate described scheduling and communication as smooth, and the interviewer as friendly and collaborative. They clarified use cases, discussed an event-driven design with Kafka fan-out, considered storage trade-offs, and solved the coding problem with an optimal **O(n)** approach after confirming the plan with the interviewer. The candidate also reported that the recruiter described the coding portion as practical rather than LeetCode-style, while the actual problem was a classic algorithm question. Because design, coding, and behavioral sections were compressed into 45 minutes, the candidate felt each section was rushed and lacked time for depth. The candidate felt their behavioral answer about feedback was less structured than intended. The rejection email cited a “different technical profile” and did not provide specific feedback. ## Community answers No community answers have been contributed yet. ## Related questions - [Explain to me what happens when you click on a web link.](https://www.aced.io/questions/5698/explain-click-web-link) - [What happens when you navigate to a website?](https://www.aced.io/questions/114/what-happens-navigate-website) - [What happens when you request a ride on Uber and is there a way to pre-process anything?](https://www.aced.io/questions/168/request-ride-uber) ## Related courses ### [Software Engineering Interview Prep](https://www.aced.io/courses/software-engineering) ![Software Engineering Interview Prep](https://images.ctfassets.net/x78yjrjc11pq/4VkuYewBHUFIVUS5oJDW5h/02e833439b1289f25f38f13f81cbdca3/adobe_stock_optimized.jpeg?w=800&h=800&fm=webp&q=75) We help candidates prepare for software engineering roles at Google, Amazon, Microsoft, Meta, Apple, and other top companies.
