Questions & Answers

As answered by people managing HackerRank and Proto.Engineer.

What makes your product unique?

Proto.Engineer's answer:

It teaches the approach, not the answer. Each algorithm is taught around one "heart line": the line the whole solution turns on. Learners remember that line and rebuild the rest with five questions, so they can solve problems they have never seen.

  • Design problems come with change requests: your design is done, then the requirement changes, like real design rounds.
  • Every practice problem runs on a real interview clock: 15 min easy, 25 medium, 40 hard, 90 design.

Why should a person choose your product over its competitors?

Proto.Engineer's answer:

Most prep sites give you more problems and their solutions. Proto.Engineer teaches how to look at a problem you have not seen before.

  • One method for any DSA problem, and one method for any design round
  • Practice in five programming languages, timed like a real interview
  • Lessons from first principles: DSA, low-level design, system design, operating systems, networks and databases in one place
  • Every written lesson is free with an account

How would you describe the primary audience of your product?

Proto.Engineer's answer:

  • Computer science students preparing for internships and placements, in India and abroad
  • Master's students facing interviews in their first semester
  • Working engineers preparing for coding, low-level design and system design rounds
  • Anyone who has solved many problems but freezes on a new one

What's the story behind your product?

Proto.Engineer's answer:

Proto.Engineer was started by a backend and distributed-systems engineer who noticed that real work never arrives as a named problem. It arrives as an incident: an order that ran twice, a page that got slow, a requirement that changed halfway. Candidates who memorise solutions get stuck the moment a problem looks new. So Proto.Engineer teaches from first principles: the approach you can change until you reach the right answer.

Which are the primary technologies used for building your product?

Proto.Engineer's answer:

A server-rendered web app with a separate content service. Lessons are prepared once and served per request, and code runs in an isolated judge that supports five programming languages.

  • How to Stop Getting Lost in Endless Resources and Stay Focused as a Developer
    This way, you transfer what you already know (problem-solving) but only change the syntax. Platforms like Hackerrank are also great to solve the same problem in different languages and learn from other people’s solutions. - Source: dev.to / about 1 year ago
  • Pick up new languages faster this way!
    Firstly, solve some common data structure problems with it. Implement some data structures like arrays, linked lists, stacks, queues, etc. You can check common problems on LeetCode, Hackerank or some other resources. - Source: dev.to / over 2 years ago
  • Offline alternative of hackerrank.com to practice coding offline
    I don't have a consecutive internet connection and I can't keep up learning process so I started practicing in hackerrank.com I have started some challenges in python and c++ there. Thus I have no internet connection so I cannot practice... Source: almost 3 years ago
