🗂️ Question banks · reported by candidates · not a course

A question bank is not a course. It is the questions candidates reported being asked in real fresher drives — paraphrased from public interview write-ups, and ranked by how many companies asked each one.

The part nobody else gives you
Not generic lists. Every course has a company module built from candidate-reported interview experiences — the round structure, the questions, and the full answer to each one. Pick a company and read a real one.
📣 Reported at Accenture · Data Analyst fresher round
See this course →COUNT(*) is 1000, COUNT(email) is 940, COUNT(DISTINCT email) is 900. What does that tell you? 📣 Accenture — reported (SQL)
Say this: "Sixty rows have a NULL email — 1000 minus 940. And among the 940 that do have one, there are 40 duplicate occurrences, since only 900 are distinct. So there are two separate data-quality problems: completeness and uniqueness."
What I'd do next: "Look at the duplicates before deciding anything — are they genuinely the same person signing up twice, or the same email with different casing and spacing, which is a normalisation problem rather than a duplication one? And I would not join on email until that's resolved, because a non-unique key multiplies rows."
Follow-up: "How do you see the duplicates?" → SELECT email, COUNT(*) FROM users GROUP BY email HAVING COUNT(*) > 1 ORDER BY 2 DESC.

What one pack actually buys
62 in-depth note lessons, 62 cheat sheets, 1,325 explained questions, 630 mock questions and 468 company questions. Tap through — every sample below is lifted straight out of a real lesson.
Learn it properly
A long-form lesson that teaches the topic from scratch — definitions, analogies, worked examples, and a model answer at the end of every section. Numbered sections, per-section reading time, answers hidden until you have tried them out loud.
Real lesson content — not a mock-up
When you type a URL and press Enter, the browser finds the server's address (DNS), opens a connection, asks for the page (HTTP request), receives text back (HTTP response), and turns that text into a page you can see (parsing and rendering). Every full-stack interview eventually touches this chain.
Think of it like this: ordering food on a delivery app. DNS looks up the restaurant's actual address from its name; the HTTP request is your order slip; the response is the parcel that arrives. Parsing and rendering is unpacking the parcel and laying the food out — the meal (the page) does not exist until that last step.

Why our answers are different
There is not one multiple-choice question in any of the 3,032 questions. Each one is written the way it is said in the room, and each answer gives you three things you cannot get from a video:
A spoken model answer in first person, with a concrete example — the words you would actually use, not a definition to memorise.
The probe that comes next when you answer well, and how to handle it. This is where most freshers fall over.
The common wrong answer, and exactly why it costs you the round. Knowing the trap is half the preparation.
Three doors
