Not just a question bank

A 1:1 mentor — D.R.O.N.A

An AI placement guru that knows the exact question you missed and teaches the gap — not generic theory. On call at 2am.

Never the same plan twice

Adaptive guided learning

Diagnose, then a 5-phase journey that rebuilds itself every week from your latest scores — your weakest topic always gets the most reps.

Features

Everything a placement-ready student needs, in one engine.

No more juggling six websites. Practice, mocks, company prep, interviews and an AI tutor — under one daily plan.

273 guided coding walkthroughs

Watch the solution build itself, line by line

For the tough problems, D.R.O.N.A narrates an AI-generated walkthrough — the approach, the edge cases, then the code revealed step by step with the lines that matter lighting up as the audio plays. Learn the how, not just the answer.

DBMS · Chapter 4 · IndexingQ 12 / 38

Explain the difference between a clustered and a non-clustered index. When would you pick one over the other?

MEDIUMindexes· tagged in Infosys 2024, TCS 2025
Answer

A clustered index physically reorders the table rows by the indexed column — so there can only be one per table. A non-clustered index keeps a separate sorted structure pointing back to the row, so a table can have many.

-- clustered
CREATE CLUSTERED INDEX ix_users_id ON users(id);
Feature 07

AI Mock Interview

Practise the real thing — voice or text

HR · Technical · Behavioural rounds with D.R.O.N.A simulating an interviewer. Probing follow-ups based on your answers, a three-bullet action plan after each session, recording you can replay.

HR round · 8 min in Live
Tell me about a time you handled disagreement on a team project.
During my final-year project two of us wanted to use Flask, one wanted Django. I scoped a 2-day spike for both…
Good — concrete enough. What was the deciding factor in the end?
Hmm, deployment effort. We had limited time so we went with what we could ship fastest.
You'll get a 3-bullet action plan + a replayable recording at the end.
Feature 08

Personalised AI tutor — D.R.O.N.A

Nudges. Never spoon-feeds.

Knows the exact question you missed, the topic you've been struggling on, and the company you're targeting. Pushes you to think, then walks you through when you ask.

I don't get step 3. Why does the LCM become 24 here?
D
Let's slow down. Step 2 gave you two cycles — 6 days and 8 days. The LCM is the smallest number both cycles fit into. 6, 12, 18, 24. 24 is the first multiple of 6 that's also a multiple of 8. That's why.

The four pillars

How D.R.O.N.A teaches you

Watch. Correct. Wait. Repeat. The engine treats you the way a master teacher would — patient with the basics, ruthless about the gap.

01

Diagnose

A 5-stage diagnostic — aptitude, verbal, reasoning, technical, coding. 90 minutes total. The honest starting line.

02

Guide

A 5-phase journey tailored to your goal — Service, Product, or a single target company. Tomorrow always knows what to do.

03

Drill

Three Topic Practices a day. Adaptive picker that weights your weakest topics. EWMA scoring, not gameable averages.

04

Graduate

Company-specific mocks and AI interview rounds. Five readiness scores tell you exactly when you're hire-ready.

How it works

How D.R.O.N.A understands you

Step one — diagnose. Step two — guide. The engine never starts blind and never gives the same plan to two students.

Step 01

Diagnostic Report

A 90-minute, 5-stage diagnostic across aptitude, verbal, reasoning, technical, and coding. Returns topic-wise scores and flags your priority gaps from day one.

Step 02

My Journey

Pick a goal — Service, Product, or a single target company. D.R.O.N.A builds a 5-phase plan, rebuilds it each week from your latest scores, and tells you exactly what to do today.
