These are candidate-submitted accounts associated with the linked companies and roles. 1. **[Amazon — 5 days ago](https://www.aced.io/experiences/amazon-staff-technical-program-manager-interview-50112d)** — Technical Program Manager, Staff / L6. “Rigorous. People reading the questions and taking notes - barely making eye contacts. Had a bar raiser - asked strategic questions. All indian team, everyone seemed overworked, stressed.” 2. **[Airbnb — 2 months ago](https://www.aced.io/experiences/airbnb-sr-staff-product-manager-interview-1413e4)** — Product Manager, Sr. Staff / L7. “The process was well-defined but the goals of each round were quite vague and ambiguous. The recruiter was unable to provide detailed insight on how to prep and what to expect in each interview” 3. **[Amazon — 5 months ago](https://www.aced.io/experiences/amazon-staff-technical-program-manager-interview-db5fb0)** — Technical Program Manager, Staff / L6. “Amazon Senior TPM interviews involve a recruiter screen, technical phone screen, and a 4 round virtual loop. Assessments focus on system design, program management, and strict adherence to Amazon’s 16 Leadership Principles. A Bar Raiser ensures hiring standards, evaluating candidates on technical depth, cross-functional delivery, and behavioural STAR responses” 4. **[Mastercard — 5 months ago](https://www.aced.io/experiences/mastercard-technical-program-manager-interview-915cee)** — Technical Program Manager, Mid Level / L4. “The interview process was highly professional and engaging. The panel conducted a comprehensive evaluation, dividing their questions across three core areas: Behavioral & Bar-Raiser: Scenario-based questions assessing leadership, problem-solving, and cultural fit. Technical Stack: Deep dives into my technical expertise, tools, and past engineering projects. Program Management: Evaluating my ability to plan, execute, and deliver cross-functional initiatives.” 5. **[Amazon — 7 months ago](https://www.aced.io/experiences/amazon-software-engineer-interview-695eff)** — Software Engineer, Entry Level / L3. “The OA was more challenging than I expected, the questions were more aligned with Competitive programming style. Recruiter was really supportive and informative. Still waiting on the next steps, which is the final round.” 6. **[Amazon — 7 months ago](https://www.aced.io/experiences/amazon-sr-staff-technical-program-manager-interview-9ecc64)** — Technical Program Manager, Sr. Staff / L7. “It was a very disciplined and clear process. Preparing for the behavioral questions took a long time. One of the interviewers decided to change the standard questions and the ones she created on the spot were very unclear. That made it difficult.” 7. **[Wells Fargo — a year ago](https://www.aced.io/experiences/wells-fargo-solutions-architect-interview-355086)** — Solutions Architect. “The interviews focused mainly on my experience, technical background, and how I approached real problems rather than overly theoretical questions.” 8. **[OpenAI — 2 years ago](https://www.aced.io/experiences/openai-software-engineer-interview-5a7d13)** — Software Engineer, Senior / L5. “A recruiter reached out to me cold by email, and the process itself matched what they told me almost exactly. I had a quick recruiter screen, then a long phone screen that was really two interviews back to back: a Playground design prompt and a coding problem around credits. After that I did a virtual onsite that was only three rounds, about four hours total, with a refactoring exercise, a past-project presentation with slides, and a leadership conversation. I ended up getting rejected, and the clearest signal I got afterward was that scale mattered a lot, especially in the project presentation round. One weird process detail is that a different recruiter reached back out to me again a few months later, so my impression was their internal tracking and cooldown handling were not especially tight at that point.” 9. **[Coinbase — 2 years ago](https://www.aced.io/experiences/coinbase-staff-software-engineer-interview-f3094b)** — Software Engineer, Staff / L6. “Interview was difficult, especially on the Beast team. It included IQ test, System design, coding a binary problem on blockchain, and behavioral, and going over a technical project i worked on. Each interview had to go really well or I wasn't gonna get the offer.” 10. **[Deloitte — 2 years ago](https://www.aced.io/experiences/deloitte-business-analyst-interview-3f8c57)** — Business Analyst, Entry Level / L3. “It was a same day interview process from start to finish - it was great experience overall to go in the morning and walk with offer at the end of the day. English proficiency was tested as well as part of separate round.” 11. **[Amazon — 3 years ago](https://www.aced.io/experiences/amazon-technical-program-manager-interview-80d292)** — Technical Program Manager, Mid Level / L4. “Smooth and well organized. I had a recruiter screen, a phone interview with a TPM covering Leadership Principles and technical scenarios, and clear communication on next steps throughout.” ## Community answers No answers have been contributed by the community yet. ## Related questions - [Take a technical project you worked on and explain it to a product marketing manager.](https://www.aced.io/questions/2254/explaining-technical-project-to-pmm) - [Explain the most complex product you have built.](https://www.aced.io/questions/958/complex-product-built) - [Tell me about the most complex project you have led.](https://www.aced.io/questions/611/most-complex-project-led) ## Related courses ### [Engineering Management Interview Prep](https://www.aced.io/courses/engineering-management) ![Engineering Management Interview Prep](https://images.ctfassets.net/x78yjrjc11pq/5AqarwlCDWmr0W7AbMJFwp/16862dab13471f5eb8728b27eb2fbc07/engineering_management_track_compressed_bbabaec4a6__281_29_9a9687c1fb.jpeg?w=800&h=800&fm=webp&q=75) We cover mock interviews, frameworks, and advice from senior candidates for engineering manager roles at Meta, Google, Amazon, Microsoft, Stripe, and other companies.
