Key Topics to Focus On

Concentrate on data structures such as arrays, linked lists, and trees. Algorithms like sorting, searching, and dynamic programming are also crucial. Debugging skills and familiarity with Amazon’s Leadership Principles will give you an edge.

Example Questions

Sample Coding Problem

Problem Description	Difficulty	Example Input	Example Output
Determine if Two Trees are Identical	Easy	Two binary trees	Yes/No
Square root of a number	Medium	x = 5	2
Kadane’s Algorithm	Medium	Arr[] = {1,2,3,-2,5}	9

Sample Debugging Task

You might encounter a task where a function fails to return the correct output. For example, a sorting function might not handle edge cases. Your job is to identify the issue and fix it within the given time.

Tip: Practice debugging code in languages like Java, C++, or Python to build confidence.

Phone Screen in the Amazon SDE1 Interview Process

What to Expect

Format and Duration

The phone screen is a critical step in the amazon sde1 interview process. It typically lasts 60 minutes and includes both behavioral and technical questions. You can expect one or two video calls with a hiring manager or team members. The interviewer may begin by introducing their role and providing context about the team. This is followed by a discussion of your background and projects. The session usually consists of 15 minutes for behavioral questions and 45 minutes for coding exercises. These coding tasks are often similar to problems found on platforms like LeetCode.

Types of Questions Asked

During the phone screen, you will encounter a mix of behavioral and technical questions. Behavioral questions focus on Amazon’s Leadership Principles, assessing how well you align with the company’s values. Technical questions include coding challenges and, occasionally, system design problems. You will solve these tasks using a shared code editor, which may lack features like syntax highlighting or auto-completion. This setup tests your ability to write clean and functional code under realistic conditions.

Preparation Tips

Practicing on Shared Editors

Familiarize yourself with shared code editors before the interview. Platforms like CoderPad or Collabedit simulate the environment you will use during the phone screen. Practice solving coding problems without relying on auto-complete or syntax highlighting. This will help you adapt to the tools used in the interview.

Communication Strategies

Clear communication is essential during the phone screen. Explain your thought process as you solve coding problems. Break down the problem into smaller steps and describe each step as you work through it. This approach helps the interviewer understand your reasoning and problem-solving skills. For behavioral questions, use the STAR method (Situation, Task, Action, Result) to structure your answers. This ensures your responses are concise and impactful.

Example Questions

Sample Coding Problem

Problem Description	Difficulty	Example Input	Example Output
Reverse a Linked List	Easy	Head of a linked list	Reversed list
Find the Longest Substring Without Repeating Characters	Medium	”abcabcbb”	3
Merge Two Sorted Arrays	Medium	[1, 3, 5], [2, 4, 6]	[1, 2, 3, 4, 5, 6]

Behavioral Question Example

• Question: “Tell me about a time when you had to make a difficult decision with limited information.”

• Tip: Use the STAR method to describe the situation, the task you faced, the actions you took, and the results you achieved. Highlight how your decision aligned with Amazon’s Leadership Principles, such as “Bias for Action” or “Customer Obsession.”

Pro Tip: Practice answering behavioral questions aloud. This will help you refine your responses and build confidence.
