Interviewing at Amazon Development Center U.S.
You should expect a multi-stage Amazon process that combines an online assessment, phone or recruiter screens, and then multiple rounds of virtual and technical interviews. Across reported steps, Amazon Leadership Principles and structured behavioral storytelling show up repeatedly alongside coding and problem-solving.
The interviews heavily emphasize SQL and Amazon Leadership Principles, with Python and STAR method also showing up as prominent topics. Interview difficulty is mostly medium and hard, and the topic mix also includes low-level design, case study analysis, quantitative reasoning, and data interpretation, plus communication and behavioral interview skills.
After the interviews, you wait for final decisions typically within three to four weeks. In the candidate reports provided here, the overall offer rate is 0.0%, so you should treat this as a high-risk loop where performance depends on both technical execution and how well you align your stories to Amazon’s Leadership Principles.
Leadership Principles and STAR are not just add-ons. In the process, your phone screen and virtual behavioral style interviews are explicitly tied to Amazon Leadership Principles, and multiple loop rounds pair Leadership Principle prompts with technical work or DSA style questions.

The interview process, end to end
5 rounds · based on 960 candidate reports- 1Online Assessment (OA)
You complete an online assessment that tests coding and logical reasoning skills. Reports describe OA coding tasks with strict timing and edge cases, followed by movement into interviews when you clear it.
- 2Recruiter Screen and/or Initial Screening
You may have recruiter screening to assess fit, motivations, and basic qualifications, plus an HR style initial screening. Separately, phone screening is described as including background discussion and Amazon Leadership Principles aligned behavioral questions.
- 3Technical Assessment and Technical Interviews
You may take a technical assessment focused on AWS related knowledge and practical experience, and it can include data science knowledge and problem-solving. Technical interviews then cover coding and other engineering tasks, with several reports describing DSA style questions and sometimes system or design oriented discussion.
- 4Virtual Interviews and Behavioral Interview
You take a series of virtual interviews that can focus on Leadership Principles and competencies, with some interviews combining technical skills and behavioral fit. The STAR method and communication skills show up in the topic coverage, and multiple reports emphasize structured STAR narratives tied to Leadership Principles.
- 5Onsite Interview and Final Decision
For some roles, you may complete onsite interviews in a single day to assess technical skills and problem-solving. After the interview rounds, you wait for a final decision typically within three to four weeks.

Do this
- Use the STAR method for every behavioral and Leadership Principle prompt. Make your answers specific and measurable, then explicitly connect the outcome to the Leadership Principle being evaluated.
- Prepare to code and explain your approach, not just provide the final answer. Multiple reports describe OA or technical rounds where success depended on clarity in problem-solving and communication.
- Practice SQL and at least one additional data-focused language like Python, since both are highly prominent in the topic data. Be ready for questions that involve data interpretation and quantitative reasoning.
- Be ready for low-level design and system-style thinking, even if the role is software or data adjacent. The topic data and multiple reports point to LLD and design conversations in addition to DSA.
Avoid this
- Do not wing your Amazon values alignment. Multiple reports describe loops as sensitive to how values-based questions are handled, and Leadership Principles are repeatedly assessed across screens and virtual interviews.
- Avoid treating the online assessment as just a formality. Reports describe cases where the OA details, timing, and edge cases strongly affected whether candidates advanced.
- Do not rely on the interviewer being perfectly aligned with your topic. One report describes an interviewer mismatch that hurt the candidate, so you should be ready to clarify assumptions and communicate fundamentals.
- Do not assume the process is purely technical. Behavioral, communication style, and work-style scenarios appear in the reported flows, and one report includes a work simulation component.

Answered from real candidate and workplace dataHow hard is the process here?
The reported difficulty split is 10.4% easy, 53.2% medium, 32.0% hard, and 4.4% very hard. That means most candidates should prepare for medium to hard technical work, plus strong Leadership Principles and STAR responses.
What topics should I prioritize for my prep?
SQL is the most prominent topic (percentile 98), and Amazon Leadership Principles is also extremely prominent (percentile 100). Python (82), STAR method (96), and low-level design (81) are also highly visible, with additional coverage of quantitative reasoning, data interpretation, and case study analysis.
How long does it take to hear a decision after interviews?
Final decisions are reported to be typically within three to four weeks after the interviews. One candidate also described a longer, month-level focus for the full loop timeline, but the formal decision timing reported is three to four weeks.
What happens after the first screening stage?
Across the reported steps, you can see an online assessment, then phone or recruiter screening, then technical assessment and technical interviews, followed by virtual interviews and behavioral interview elements. The process also includes onsite interviews for some roles, but the most consistent pattern is leadership plus technical rounds.
Is there an offer rate you can expect?
In the aggregated candidate reports provided here, the offer rate is 0.0%. That does not mean you personally cannot succeed, but it does mean you should assume very low outcomes in this dataset and prepare accordingly for both technical and values components.
Should I re-apply if I get rejected?
The data provided here does not include re-application guidance or timelines. If you want, tell me your target role and stage you reached, and I can help you turn the reported failure modes into a concrete re-prep plan based only on what shows up in these reports.
