Position: SDE2 at Amazon
Location: Europe | UK
Date: Oct'21

Online Assessment:
~ 50 Behavioral questions (MCQ style)
Algorithm question:
Two coding questions
Decode a string which was encoded using zigzag encoding
Don't remember this question but was an LC Medium

**2nd technical phone screen (1 hours):
**
Started with behavioral questions and then a variation of two sum problem and a discussion on time and space complexities for quicksort & mergesort

Onsite (4 rounds):
All rounds began with 20 minutes of leadership principles questions.

First Round: Tiny URL (Choice of DB, Postgres Transaction ids, Hash Indexing, and overall architecture)
Second Round: Variation of Jump Problem (1 and 2 on LC)
Third Round: OOD round, I personally felt this was more focussed on the choice of Data Structures and clean coding. The problem was to design an adoption shelter for animals.
Fourth Round: : Finding the K longest standing product in a log of product id and timestamps. It was a variation of k most frequent elements (or atleast that is how I solved it)

Result:

Received a verbal confirmation for the offer :)
I have to now pick a location and the team. I'm confused between Amsterdam (Amazon Fintech) and Berlin (Ratings & Reviews). Any pointers will be of great help!
I am not considering London cuz I've heard that Amazon doesn't pay that well in London.
