How it works

Three steps. Then you just show up every day.

  1. 01

    Tell it where you are going

    Pick from 20 role blueprints or choose from 157 engineering tracks across 12 disciplines. Tell it how many hours a day you really have, and the curriculum engine maps out your exact daily schedule.

    Choosing learning tracks for a goal
  2. 02

    Get a plan that fits your calendar

    Prep lays out every topic across your available days, interleaves tracks so nothing goes stale, and books revision back in three, seven and fourteen days later. Rest days stay rest days.

    Today view with the day’s tasks
  3. 03

    Learn it, run it, remember it

    Each topic opens a workspace: an explanation that starts from zero, worked examples you can run, diagrams, a quiz, your own notes and flashcards that come back when you are about to forget.

    A topic workspace with the overview and AI lesson

Product

Built around the way you actually study.

Not a video library. A workspace per topic, a plan across topics, and a tutor that knows both.

Explanations

Every topic starts from zero, in the language you code in.

Definition, why it matters, a real-world example, a step-by-step walkthrough and code in Python, Java, TypeScript, Go, C++, Rust, Kotlin, Swift, Dart or SQL. React topics come back as TSX, DevOps as shell and YAML, and AI engineering with runnable Python.

Worked examples with numbered steps and runnable code

Practice

Run the code where you read it.

A code runner for six languages sits inside every problem. Try the worked example, break it on purpose, log the attempt with your approach and complexity, and keep the history on every device.

The code runner with output

System design

System design the way interviews actually ask it.

Requirements, back-of-envelope estimates, an architecture diagram, data model, APIs, the key flow as a sequence diagram, a deep dive, trade-offs, and how to present it in forty-five minutes. Diagrams are editable, not pictures.

Mock interviews

An interviewer who talks back, and a scorecard that tells the truth.

Pick a round, a level and a length. The interviewer speaks the questions, listens to your answers, pushes on gaps, reads the code you share and wraps up when the clock runs low. Then you get a hiring-committee scorecard: dimensions, verdict, model answers and what to revise.

Setting up a mock interview round

Revision

Flashcards that come back at the right time.

Cards are made from what you actually studied and scheduled with spaced repetition. Today shows what is due; a session takes minutes with keyboard shortcuts.

A flashcard study session

Tutor

A tutor that has read your notes.

Ask anything about the topic you are on. For DSA it gives hints in five levels instead of the answer; for design it reviews your architecture. Drag it, resize it, keep it open while you work.

The AI tutor beside a topic

Job hunt

Applications, follow-ups and interviews, in the same tab.

Track every application on a board or a table, import recruiter emails, sync Gmail, and keep prep notes next to the company they are for. Your study plan and your pipeline finally share a calendar.

Why you can trust it

Everything on this page can be checked.

No invented numbers, no fake reviews, no countdown timers. Here is what actually protects you when you pay ₹299.

Real openings, real links

Every opening comes from the company’s own careers feed with the original application link. Listings that disappear at the source disappear here.

One payment, no auto-renew

A pass is a single Razorpay payment. No card on file, nothing renews by itself, and buying another pass simply adds its days.

Receipt for every purchase

A receipt with the Razorpay payment id is emailed to you and kept under Settings → Billing, so support and refunds are straightforward.

Refunds for real problems

Duplicate charges and any failure to deliver access are refunded in full, usually within 5 to 7 business days. The policy is public.

Your keys, your data

AI runs on your own key, encrypted at rest and sent only to the provider you chose. Export your data any time; delete the account yourself.

A person answers

hello@evolw.in reaches the team that builds Prep. No ticket bots, no outsourced support.

Pricing

Pick a pass. Pay once.

Every pass includes everything. No subscription, no auto-renewal, no card kept on file.

Paid through Razorpay with UPI, cards or net banking; a receipt with the payment id is emailed to you. Buying another pass while one is active adds the days to the end.

Who it is for

Engineers with one to eight years of experience preparing for product-company and GCC rounds, and final-year students who want a plan instead of a playlist.

Why passes instead of a subscription

Interview prep has a finish line. Buy the stretch you need, sit the interviews, and never think about cancelling. Less than a single mock-interview session elsewhere.

If it does not work for you

Duplicate charges and access failures are refunded in full; unused passes have a cooling-off window. Details are in the refund policy, and hello@evolw.in answers.

Questions

Straight answers.

Yes. Create a free account and use Job Discovery (a sample of live openings), the resume workspace, the tracker and the general curriculum browser. A pass unlocks the learning workspaces, the code runner, AI features, the full ranked job feed and job-specific mock interviews.

Payments are processed by Razorpay (UPI, cards, net banking); Prep never sees or stores your card or UPI details. Every purchase gets a receipt with the Razorpay payment id, emailed to you and always available under Settings → Billing.

Duplicate charges and any failure to deliver access are refunded in full; the refund policy also has a cooling-off window for passes that were not used. Write to hello@evolw.in with the payment id from your receipt and a human answers, not a bot.

Directly from each company’s own careers feed, refreshed daily, with the original application link. Nothing is copied from job boards and no opening is invented: if a company stops listing a role, it disappears here too. The counts on this page are read live from the database.

No! Turnkey AI access is included out of the box on every pass for mock interviews, resume analysis, and tutoring with zero setup. If you are an advanced user with your own Groq, Gemini, or OpenAI keys, you can also connect them in Settings.

Prep features 157 complete tracks across 12 disciplines: AI & Generative AI (LLMs, RAG, Agents, MLOps, Computer Vision), Backend Frameworks (Spring Boot, Node.js, FastAPI, Go, Django, gRPC), Frontend & Web (React, Next.js, TypeScript, Vue, Svelte, Web Performance), Cloud & DevOps (AWS, Azure, GCP, Docker, Kubernetes, Terraform, CI/CD), Mobile (Flutter, React Native, Kotlin, Swift), Data Engineering & Science (Spark, Kafka, Airflow, dbt, Pandas, Power BI), Cybersecurity (AppSec, Cloud Security, Threat Modeling), CS Fundamentals (OS, Networks, DBMS, Distributed Systems), and Software Engineering Interviews (DSA, HLD, LLD). You can code in Java, Python, C++, Go, TypeScript, JavaScript, Rust, Kotlin, Swift, Dart, and SQL.

Yes. Prep includes 20 pre-built Career Path Blueprints for roles like AI Engineer, Generative AI Engineer, Full-Stack Developer, Frontend Developer, Java Backend Developer, Python Backend Developer, DevOps Engineer, Cloud Architect, Flutter Developer, Data Scientist, Data Engineer, and SWE Interview Prep. You can use any blueprint as-is or customize it by adding, removing, or reordering topics to match your exact interview timeline.

No. You buy a pass for 90 days, 180 days or a year with one payment. Nothing renews by itself, and buying another pass simply adds its days to the end of the current one.

Nothing is deleted. Your plan, notes, attempts and mock-interview reports stay in your account. The learning workspaces, AI and the code runner pause until you pick a new pass.

Pick a round such as DSA coding, system design, React or behavioural, a difficulty and a duration. An AI interviewer asks questions out loud, listens to your answers, pushes back on gaps, and gives you a scorecard with model answers and topics to revise.

Yes. Everything syncs to your account, so the plan you build on a laptop is on your phone in the morning, including attempts and notes.

Prep is built and run by Evolw (www.evolw.in), a small product team in India. There is one support address, hello@evolw.in, and it is read by the people who build the product.

Your plan, notes, resume versions and reports belong to you: export everything as a file from Settings at any time, and delete the account yourself from the Data Controls page. AI keys are encrypted at rest; resumes never leave your account.

Your next interview is closer than the end of your bookmarks folder.

Start free with live openings and your resume. Add a pass when you are ready to prepare properly.
