The reported sequence included a recruiter screen, hiring-manager interviews, case-heavy interviews, and separate behavioral interviews. Almost every round blended casing and behavioral assessment. The interviews were candidate-led: one interviewer was described as highly collaborative, while another was more reserved and watchful, particularly during cases. The contributor identified story, stakeholder management, and demonstrating genuine AI-native capability rather than merely using buzzwords as major themes in the process. ## Community answers No community answers have been contributed yet. ## Related questions - [Tell me about the best engineer you ever hired.](https://www.aced.io/questions/7266/describe-best-engineer-hired) - [What's your approach to prompt engineering?](https://www.aced.io/questions/5603/prompt-engineering-approach) - [Tell me about the hardest technical problem you've solved.](https://www.aced.io/questions/6483/hardest-technical-problem) ## Related courses ### [Product Strategy Questions](https://www.aced.io/courses/product-strategy) ![Product Strategy Questions](https://images.ctfassets.net/x78yjrjc11pq/5hHtTyOypgyKA7R3fxMlyl/dde193ecc09baabd8304c3aec25483f2/product_strategy_course_ab4d3cf294.jpeg?w=800&h=800&fm=webp&q=75) Our Product Strategy Questions course explains how product strategy interviews differ in the AI era and how to approach these rounds effectively within the new rules. ### [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) Our Software Engineering Interview Prep course helps candidates prepare for software engineering roles at Google, Amazon, Microsoft, Meta, Apple, and other top companies.
