Let’s take a look at some common Amazon SDE 2 interview questions to help you prepare for your interview. We’ll briefly look at the interview process, followed by questions on coding, systems design, and Amazon’s leadership principles.
Here’s what we’ll cover:
The Amazon SDE 2 interview process evaluates your coding, problem-solving, and systems design skills. The process typically consists of four main rounds.
The Online Assessment, or OA, is the first step in the process. Typically, recruiters from human resources will contact you before the OA to understand your interest in the role, expectations, and prior professional experience.
The Online Assessment is a remote coding interview that lasts about 1.5 hours. The hiring manager in this round will ask you to solve 1-2 coding problems in core data structures and algorithms. The interview typically takes place via Amazon Chime.
In this round, the hiring manager will watch your code live and ask you questions about your approach. You’re also evaluated on your ability to solve all edge and test cases.
You can also expect a question about Amazon’s core leadership principles.
Some tips to crack the Online Assessment -
The Technical Phone Screen round usually involves answering Amazon SDE 2 interview questions on systems design and coding. You can expect one question from each category. Design questions are low-level, while the coding problems are usually complicated problems from Leetcode. Brushing up on core design concepts and DSA concepts is crucial to getting past this round and being called for the On-site interview.
An important point to note is that the Technical Screen doesn’t happen all the time. If you’re already asked LLD (low-level design) questions, and coding problems in the Online Assessment and your performance is satisfactory, you’ll be directly invited to the On-site interviews without needing to appear for the TEchnical Screen.
The On-site is the last phase in the Amazon SDE 2 interview process. Also known as the Loop, it typically comprises 3-4 rounds where the Amazon SDE 2 interview questions that are asked evaluate your coding skills, design skills, and understanding of Amazon’s leadership principles.
