Now practice all your interviews before giving the real one

( Coding practice )

Coding interview questions, checked like the real test.

Solve in the language you'll use on the day. Your code runs against hidden tests, so a pass here means something.

Start practising
1

Pick a list

Work through the 100-day challenge, or a company's list — Google, Amazon, Microsoft, TCS and more.

2

Run, then submit

Run checks your code on the examples. Submit runs the hidden tests too, like an online assessment.

3

Learn from it

See which test your code failed. Stuck for good? The solution is one deliberate click away.

( What you get )

Practice that holds up on the day.

Six languages

Python, JavaScript, TypeScript, Java, C++ and Go. Your code runs on our servers, not in the browser.

Hidden tests

Like a real assessment, you don't see every test. A pass means your code holds up, not that it fits the examples.

Company lists

Questions grouped by the companies known to ask them, so you practise for the interview you have booked.

A 100-day challenge

One question a day for 100 days, so practice becomes a habit. Days 1–30 are free.

Solutions when you ask

The answer stays hidden until you choose to see it, and every submission you make is saved.

One small pass

The Practice pass opens every list for ₹199 a month in India, $5 elsewhere. Starter and Pro already include it.

Questions

Good to know

Is coding practice free?

Days 1–30 of the 100-day challenge are free with an account. The Practice pass (₹199 a month in India, $5 elsewhere) opens every list, including the company lists, and the Starter and Pro interview plans include it.

Which languages can I use?

Python, JavaScript, TypeScript, Java, C++ and Go. You can switch language on any question.

How is my code checked?

It runs on our servers. Run tries it on the question's examples and shows each result; Submit also runs hidden tests and stops at the first one that fails, the way an online assessment does.

How is this different from a mock interview?

Coding practice is you and the editor, at your own pace. A mock interview is a live voice round with an AI interviewer who asks about your CV, sets a coding exercise and scores every answer.
