My Amazon Frontend Engineer Interview Experience

Hi everyone, here’s a quick overview of my interview process for the Frontend Engineer I role at Amazon.

Background

I was contacted by Amazon (I’m an ex-intern) regarding an SDE role, but they mentioned an opening for Frontend Engineer I or Analyst. I applied for the frontend role.

Process

1. Mettl Online Assessment (OA)

The OA included:

• 1 coding question
• MCQs on topics like DSA, OOP, Networks, DBMS, SQL, Software Testing, etc. (~5 questions per topic).
  I performed well and moved to the next stage.

2. Frontend Assignment

I completed a frontend-specific OA assignment and was invited for interviews.

3. Interviews

Round 1: DSA

1. Triplet with sum 0 in a BST:
   • Approach: In-order traversal → Sorted array → 3Sum algorithm.
2. Row with max 1's in a row-wise sorted matrix (m, n = 100,000):
   • Brute force → Optimized with a two-pointer approach.

Round 2: Frontend

• Task: Recreate a given UI live using HTML and CSS.
  • I used React.js + Tailwind CSS (my comfort zone) but also attempted HTML/CSS.
• Feedback: The interviewer noted my strong SDE fundamentals and asked why I wasn’t pursuing SDE roles.

Outcome

I received a rejection email. I wasn’t planning to leave my current company but applied to test my skills.

Key Takeaways

1. DSA remains critical, even for frontend roles.
2. Brush up on HTML/CSS for frontend-specific interviews.
3. Avoid over-relying on tools like Copilot for live coding tasks.

Overall, a great learning experience! Hope this helps others preparing for similar roles.
