Inside the Practice Feed: How Topalupu Personalises Your Interview Prep

What Is the Practice Feed?

Why We Built It

The Problem with Traditional Practice

*Which problems should I solve for Google vs. Amazon?*
*How many system design scenarios do I need?*
*Am I spending too much time on Easy problems?*
*Which problems have I already completed?*

The Practice Feed Approach

How the Practice Feed Works

Personalised Problem Discovery

Your target companies — each problem is tagged with the companies that have asked it
Your target roles — Software Engineer, Senior SDE, ML Engineer, etc.
Difficulty progression — a healthy mix of Easy, Medium, and Hard to build confidence progressively

Three Interview Pillars in One Feed

TabWhat It ContainsWhy It Matters Coding30+ algorithm and data structure problems per companyThe core technical round — always present System DesignReal-world architecture scenarios at scaleRequired for mid-level and senior roles BehavioralCompany-specific culture and values questionsOften the tiebreaker between strong candidates

Smart Filtering and Sorting

Difficulty filters — toggle between All, Easy, Medium, and Hard
Saved problems — bookmark problems you want to revisit
Topics — filter by specific patterns like Arrays, Dynamic Programming, Trees, or Graphs
Sort by newest — see recently added problems first
Company match badges — green "MATCHED" badges highlight problems from your target companies
