How does Amazon decide to hire?

Amazon's decision to hire is based on a structured evaluation process that assesses both technical skills and cultural fit with the company’s Leadership Principles. The hiring decision is made after a series of interviews, culminating in a debrief session, where interviewers discuss the candidate's performance and reach a consensus. Here's a detailed breakdown of how Amazon decides whether to hire a candidate:

1. Technical Evaluation

For technical roles, Amazon focuses heavily on the candidate’s ability to solve complex problems efficiently and effectively. Interviewers assess the following areas:

• Problem-Solving Skills: How well the candidate approaches and solves coding challenges, including the ability to optimize solutions.
• Coding Proficiency: Clean, efficient, and scalable code.
• System Design (for mid-level and senior roles): Ability to design scalable, high-performance systems with considerations for reliability and fault tolerance.
• Algorithm Knowledge: Understanding of data structures, algorithms, and how to apply them in real-world problems.

For non-technical roles, the focus might be more on domain-specific skills, such as product management, data analysis, operations, or customer service expertise.

2. Behavioral Evaluation (Leadership Principles)

Amazon places a strong emphasis on how well candidates align with their 14 Leadership Principles, which guide decision-making across the company. Interviewers assess behavioral traits through questions that explore past experiences:

• Customer Obsession: Does the candidate prioritize customer needs in their decision-making?
• Ownership: Does the candidate take responsibility for their projects and outcomes?
• Bias for Action: Is the candidate decisive and willing to take quick actions in ambiguous situations?
• Dive Deep: Does the candidate pay attention to details while maintaining a high-level view of the problem?

Amazon evaluates candidates' responses to behavioral questions using the STAR method (Situation, Task, Action, Result) to determine how well they reflect these principles.

3. Bar Raiser Input

The Bar Raiser plays a critical role in the hiring process. This Amazon employee, who comes from a different team than the one you’re interviewing for, ensures that hiring standards remain high. They focus on:

• Raising the Hiring Bar: The Bar Raiser must believe that hiring you will raise the overall bar for talent at Amazon.
• Long-Term Fit: They evaluate if you’ll succeed not only in the short term but also in the long run at Amazon, based on your skills and cultural alignment.

The Bar Raiser has significant influence in the final decision and can veto a hire if they believe the candidate doesn’t meet Amazon’s standards.

4. Debrief Session

After the interviews, all interviewers, including the Bar Raiser, meet for a debrief session. During this session:

• Each interviewer presents their feedback, including ratings on technical performance and behavioral fit.
• The Bar Raiser leads the discussion, ensuring a fair evaluation based on Amazon’s hiring criteria.
• Interviewers discuss the candidate’s strengths and weaknesses, and whether they demonstrated the required skills and Leadership Principles.

The goal of the debrief session is to reach a consensus on whether the candidate should be hired. Each interviewer will typically give a "hire" or "no hire" recommendation, and the Bar Raiser ensures the final decision aligns with Amazon’s high standards.

5. Final Decision

The final hiring decision is based on a combination of:

• Technical Skills: Whether the candidate demonstrated strong problem-solving abilities and technical expertise.
• Leadership Principles: How well the candidate embodies Amazon’s Leadership Principles in their answers and approach to work.
• Bar Raiser’s Input: The Bar Raiser’s opinion often carries significant weight in the final decision.

If the majority of interviewers and the Bar Raiser agree that the candidate meets or exceeds Amazon’s hiring bar, an offer is extended. If there are concerns about cultural fit or technical skills, the candidate will not be hired, even if they performed well in some areas.

Summary of How Amazon Decides to Hire:

1. Technical Performance: Candidates are evaluated on their ability to solve problems, code efficiently, and design systems (for senior roles).
2. Cultural Fit: Alignment with Amazon’s Leadership Principles is crucial.
3. Bar Raiser’s Approval: The Bar Raiser ensures that only candidates who raise Amazon’s talent bar are hired.
4. Debrief and Consensus: The decision is made in a debrief meeting where interviewers discuss and vote on the candidate’s performance.

To succeed, candidates need to excel in both technical and behavioral areas, and demonstrate strong alignment with Amazon’s Leadership Principles.
