Amazon SDE2 L5 Interview Experience
The process started with an online assessment, after which I was contacted by a recruiter. There was also a prep discussion before scheduling the interviews. The loop consisted of four rounds, each around an hour long, with a mix of technical and leadership principle discussions.
Round 1 (DSA + LPs):
The DSA part had two questions.
The first one was a variation of string validation problem involving checking whether brackets are balanced.
The follow-up was to find the minimum number of removals required to make the string valid, which leaned towards a BFS-based approach.
The leadership discussion in this round focused on learn & be curious and deliver results.
Round 2 (LLD + LPs):
This round was centered around designing a pizza ordering system using a decorator-style approach.
Leadership questions here were around ownership and customer obsession.
Round 3 (HLD – Hiring Manager + LPs):
This round focused on designing a video streaming platform like Netflix.
Leadership questions were more around insist on highest standards and earn trust.
Round 4 (Bar Raiser – DSA + LPs):
This round had a variation of the classic 2-sum problem.
The follow-up made it more interesting: if an exact sum is not possible, find two items whose sum is максимально close but does not exceed the target.
A big focus in this round was not just solving the problem but asking the right clarifying questions upfront.
The leadership discussion here revolved around invent & simplify and dive deep.
Overall, the process emphasized both problem-solving and how well you align your experiences with leadership principles.
Verdict: Hire
