Grokking Amazon Coding Interview

It is the 50 coding questions asked most frequently in Amazon interviews. Each is a problem lesson you attempt in an in-browser editor, followed by a solution lesson with the approach, a step by step algorithm, a walkthrough, code in six languages, and the complexity analysis.

Engineers with an Amazon loop coming up, at any level. It assumes your data structures and patterns are already in place and gives you targeted practice for the final stretch rather than teaching the fundamentals again.

Fifty, among them Longest Common Prefix, Path Crossing, Relative Sort Array, Leaf-Similar Trees, Make Array Zero by Subtracting Equal Amounts, Next Greater Element II, Count the Number of Good Subarrays, Maximum Length of Subarray With Positive Product, Largest Submatrix With Rearrangements, Concatenated Words, Constrained Subsequence Sum, Count Vowels Permutation, and Count All Valid Pickup and Delivery Options.

15 easy, 25 medium, and 10 hard. Amazon runs a lot of interviews at a fairly consistent bar, which sits mostly in the medium band, so that is where most of the practice is concentrated.

They are not covered here, and you should not treat that as a detail. Amazon weights its behavioral round unusually heavily, every interviewer probes the Leadership Principles, and strong coders are rejected on that round routinely. This course prepares the coding side; pair it with Grokking Modern Behavioral Interview and prepare specific stories against the principles.

Python, Java, C++, JavaScript, Go, and C#. Every solution is given in all six, so you can practise in the language you plan to use on the day.

For the coding rounds it is strong, focused preparation, but an Amazon loop is wider than coding: there is a system design component at most levels and a heavily weighted behavioral element throughout. No list can promise the questions you will get. The purpose of these 50 is to make the underlying shapes quick to recognise.

Grokking the Coding Interview teaches pattern recognition from scratch across more than 300 problems. This narrows to one company and assumes the patterns are there, so it works best as the final phase of preparation rather than the first.

Text-based, with runnable code and diagrams on the solutions. Attempting, running, failing, and rereading the walkthrough is the cycle that builds recall, and it is far quicker on a page than in a video.
