Amazon Dublin Frontend Engineer (New Grad) – Rejected After Phone Screen

Wanted to share my interview experience so it helps others in the process.

Timeline: • Applied for SDE-1 (India AUTA) for multiple Roles/Job IDs on June 25 → Got 2 OAs. • Applied for Frontend Engineer Dublin on July 23 → Directly got Phone Screen (probably skipped OA because of previous interest form).

Total Rounds: • Round 0: Resume Shortlisting • Round 1: Online Assessments (OA) • Round 2: Phone Screen

OA 1 (India SDE-1): • Difficulty: Medium-Hard • Topics: DSA-heavy — I can’t share exact Qs, but expect standard high-quality Amazon-style problems. • Time: Almost took 50+ minutes.

OA 2: • Difficulty: Medium • Topics: Arrays, Sliding Window, HashMaps — time-sensitive, edge-case heavy. • Time: Was able to complete in 13 minutes.

Phone Screen (Dublin FEE): • DSA Problem: Focused on Binary Search + Prefix Sum, with optimal solution via Segment Tree. I gave a brute-force O(N) first, then tried optimizing (Binary Search in O(log N)) — implemented ~50%. Couldn’t finish fully due to time constraints. • LPs (Leadership Principles): Took 40+ minutes. Very important. Interviewer asked to structure responses using STAR and go deep into past experiences. No frontend questions.

Outcome: Rejected.

My Reflection: LP part went well. Interviewer was supportive. I struggled a bit with DSA optimization under time pressure. Was my first serious interview at this level — learned a ton.

📌 Will keep applying. This process gave me clarity on what to improve next.
