How long is Amazon coding interview?

The Amazon coding interview typically lasts between 45 to 60 minutes per round. Depending on the role and level, you may have multiple rounds focusing on coding challenges. Here's a breakdown of the process:

1. Phone Screen (Technical Round)

• Duration: 30 to 60 minutes
• You’ll usually be asked to solve one or two coding problems in real-time, often on a collaborative coding platform. This is your first technical assessment.

2. Onsite or Virtual Interview

• Duration: 4 to 5 hours (with multiple rounds)
• For technical roles, the onsite (or virtual) interview typically consists of 4-5 rounds, each lasting 45 to 60 minutes. At least 2 to 3 of these rounds will focus on coding challenges, where you’ll be tested on algorithms, data structures, and problem-solving skills.
• Additional rounds may focus on system design (for senior roles) and behavioral interviews based on Amazon’s Leadership Principles.

3. Technical Rounds (Coding Focus)

• Duration per round: 45 to 60 minutes
• Each coding round will involve solving one or two algorithmic problems. You’ll be expected to explain your approach, write efficient code, and discuss any potential optimizations.
