Study guides: build one for the role

A study guide pulls the questions and concepts that matter for a role into one place you can read top to bottom. Not a pile of random questions. The ones that fit the job you're prepping for.

Here's how to build one and what each option does.

What a study guide is

PrepVault compiles a guide from the question bank and your flashcards, grouped by category and topic. You pick what goes in and how deep it goes, then read it like a document instead of clicking through cards one at a time.

Building a guide for a role is part of the free toolkit. The AI study plan that sequences it into a day-by-day schedule is a Pro feature.

Choosing what goes in

The builder has a toggle for each kind of content: full explanations, key-concept summaries, code examples, the common mistakes people make, the follow-up questions an interviewer asks next, and quick-recall question and answer pairs. Turn off what you don't need so the guide stays focused.

You can also filter by difficulty, from foundational to expert, so someone prepping for a staff role isn't wading through entry-level material.

The study guide builder with content toggles and a difficulty filter — Pick the content and the difficulty. The guide is built to match.

How to actually use it

Read it once end to end to find the gaps, then go back to the parts you stumbled on. A study guide is for finding what you don't know. Flashcards and quiz mode are for drilling it until it sticks.

Build a fresh guide per role rather than one giant catch-all. A guide tuned to one job's stack is shorter and far more useful than everything you might ever be asked.
