Amazon Software Developer interview questions

Only got to OA Two coding questions. Medium difficulty but could not do it in time or my solution took too long. Needed to prepare more for it. I used neet code for a few weeks.

Amazon's interview process typically consists of multiple stages designed to assess both technical skills and behavioral competencies. Here’s a general breakdown: --- ### **1. Online Assessment (OA)** For many technical roles, Amazon starts with an online coding test. This is usually conducted on platforms like **Hackerrank or Codility**. It includes: - **Coding Problems** (DSA-focused, Leetcode Medium/Hard) - **Debugging Tasks** (Finding errors in given code) - **Work Simulation** (Situational judgment tests) - **Technical MCQs** (Related to data structures, algorithms, and system design) --- ### **2. Phone Screen (1–2 Rounds)** If you pass the OA, the next step is a phone interview with an Amazon engineer or hiring manager. - **Duration**: ~45–60 minutes - **Focus**: - Coding questions (DSA, problem-solving) - Behavioral questions (based on **Amazon Leadership Principles**) - **Platform**: Usually conducted via **Amazon Chime or a shared coding editor**. --- ### **3. Onsite Interviews (4–5 Rounds)** If you clear the phone screen, you’re invited for onsite interviews (or virtual rounds for remote candidates). These are **behavioral and technical interviews** conducted by different Amazon employees. #### **Technical Rounds (3–4)** - **Coding Questions** (Data Structures & Algorithms, System Design) - **System Design** (For experienced roles) - **Object-Oriented Design** - **Problem-Solving Approach** #### **Behavioral Round ("Bar Raiser")** - Conducted by a trained Amazon interviewer ("Bar Raiser") who ensures candidates meet Amazon’s hiring standards. - Heavy focus on **Amazon’s 16 Leadership Principles** (e.g., **Customer Obsession, Ownership, Deliver Results**). - STAR Method (Situation, Task, Action, Result) is recommended for answering. --- ### **4. Hiring Decision** After the onsite interviews, Amazon recruiters and interviewers discuss your performance in a debrief meeting. - If selected, you’ll receive an **offer letter**. - If not, they may suggest **reapplying after 6–12 months**. --- ### **Key Tips for Success** - Practice **Leetcode Medium/Hard** (especially graphs, trees, dynamic programming). - Prepare **system design** (for mid/senior roles). - Understand and apply **Amazon’s Leadership Principles**. - Use the **STAR method** for behavioral questions.
