The problem

The questions are out there.Scattered across thousands of threads.

Candidates post what they were just asked. On Blind, on LeetCode Discuss, on 1Point3Acres. Half in shorthand, half in Chinese.

We read all of it, sort it by company and round, and solve every one.

Here’s what that looks like

How it works

How we know
what they ask.

Every week, candidates walk out of a loop and post exactly what they got. The best write-ups are in Chinese, behind forum logins, gone from the front page in a day. We go and get them.

The problems a company keeps coming back to go to the top. Each one gets the full answer: intuition, a traced example, the code, the diagram. We checked 406 claims about how these companies interview. 51 were wrong, and they're not in the guides.

The whole answer.

Every problem comes with the intuition, a traced example and the code. Every design comes with the diagram you'd draw on the whiteboard.

The Two Sum solution in the Google guide: the intuition, a traced example and the approach — **Coding**Two Sum, traced index by index before a line of code.

The Design YouTube diagram in the Google guide, with the write path and the read path — **System design**YouTube's write path and read path, drawn the way you'd draw them.

Google's behavioral questions grouped by the trait each one tests — **Behavioral**Google's G&L questions, grouped by the trait each one tests.

Fair questions.

How is InterviewLegend different from LeetCode?

LeetCode gives you thousands of random problems with no structure. InterviewLegend is the structured LeetCode alternative: company-specific roadmaps that show you exactly which patterns and problems each company actually asks, organized into a clear preparation path from application to offer.

What makes your guides 'company-specific'?

Each guide is built from real interview experiences and patterns specific to that company. Google focuses on different patterns than Amazon. Meta's system design expectations differ from Netflix's. We break down exactly what each company looks for, not generic advice that applies everywhere.

How much content is free vs premium?

Every company guide has at least six full lessons free: the process overview, how hiring decisions get made, a prep plan, and an overview of every round. Many guides also give away a full coding lesson and a worked system design. Premium unlocks complete solutions with explanations, all 1438 practice problems, system design deep dives, behavioral frameworks, and negotiation playbooks.

Do you cover system design and behavioral, or just coding?

We cover the complete interview: coding patterns, system design, behavioral prep, resume optimization, and offer negotiation. Each section is tailored to what that specific company expects and evaluates.
