The interview process at Amazon Web Services (AWS) typically consists of several stages designed to evaluate both technical skills and cultural fit. Here’s an overview:

Initial Screening: This usually involves a phone or video call with a recruiter to discuss your background, experience, and interest in AWS.

Technical Phone Screen: One or two phone interviews with an AWS engineer focusing on technical skills, including coding, algorithms, and system design. You may be asked to solve problems using an online coding platform.

Onsite Interviews: A series of interviews at an AWS office or virtually, including:

• Technical Interviews: In-depth coding, system design, and problem-solving questions. This can include whiteboarding sessions or live coding.
• Behavioral Interviews: Questions based on the Amazon Leadership Principles to assess cultural fit. You’ll need to provide examples from your past experiences.
• Role-Specific Interviews: Depending on the position, you might face additional interviews focusing on domain-specific knowledge.
