    A practical map of codinzhub.com, a completely free platform for college students: where to practise, where to research a company, where your coins go, and what is on the free Premium pages (college-wise CTC data, CGPA cutoffs and PYQs). Every link below opens the live site, and the blog links jump to the deeper guides.

    In this guide

    • Every main page and what it is for
    • How company pages are organised into tabs
    • What Premium adds on top of the free library

    Main pages

    PageWhat it is for

    Company pages

    Each company page has tabs for Questions, Interview Experiences and About. The directory is alphabetical and keeps growing, so search it for your target company rather than scrolling. Some examples:

    CompanyWhat you will find
    GoogleLatest OA questions, interview experiences and the 55-report Google guides on this blog
    AmazonLatest OA questions and interview experiences
    MicrosoftLatest OA questions and interview experiences

    Shortcuts worth learning

    • Keyboard: press Ctrl + K (or /) inside the blog to jump to any article
    • Article URLs: every post has a stable anchor — this one is #blog-33 — so you can bookmark the ones you re-read
    • Practice loop: question page to solution to company page to the matching blog guide, in that order

    What Premium adds

    Premium is completely free, with no paid tier. The library answers "what was asked", and the college-wise placement data page answers "can I even apply, and what does it pay" — CTC figures, CGPA eligibility cutoffs and OA patterns — while the resources page holds the PYQs. It is a separate layer from coins: coins unlock individual items, Premium is the placement view. Full walkthrough in CodinzHub Premium explained.
