Flipkart SDE: the machine coding, from your Résumé to the report
What a mock looks like in the room, step by step. The panel, its order, the form and the criteria are the real round's; the words and numbers are illustrative.

You fill in your Résumé once
The interviewer has your résumé open. Expect questions on anything you listed — every project and every tool — and a level pitched to the role you name at Flipkart.

In the order the real one moves: problem, then approach, then code, then test. Follow-ups come from what you just said.

You write the code; the interviewer reads it
This round's real version runs your code, so it runs here too — the interviewer sees what it printed.

The report says what to fix
Scored on the 5 criteria this round is assessed on, with every line of your Résumé marked as held up, shaky or not yet asked. A practice estimate, never a forecast.

Nothing to buy first. Pick the round, fill in your Résumé, and the interviewer is ready. Your recording, if you ask for one, never leaves your device.
One engineer who sets the problem and reviews the code.
The machine-coding round asks for working, extensible code for a small real system within a fixed time — design and code quality count as much as getting it to run.

Flipkart hires engineers through an online test, a problem-solving and data-structures (PSDS) round, a machine-coding round where you build a working program in about 90 minutes, a design round for SDE-2 and above, and a hiring-manager conversation. In order: Machine coding (coding, 90–120 minutes); PSDS (coding, 60 minutes); System design (SDE-2 and above) (system design, 60 minutes); Hiring manager (behavioural, 45–60 minutes).
What does the interviewer assess?
Working code, Object modelling, Extensibility, Code quality, Edge cases. Not published by Flipkart; these are what its machine-coding round is widely reported to assess.
What will I be asked about?
The interviewer has your résumé open. Expect questions on anything you listed — every project and every tool — and a level pitched to the role you name at Flipkart. The Résumé lines it draws on: name, role and level you're interviewing for, education, experience, projects, languages and tools, and more.
Can I practise the Flipkart SDE interview online?
Yes. The Practice Studio runs a mock of each round the way the real one moves — a problem set in a shared code editor the interviewer reads as you write — and scores you on the same criteria. You can also book a real interviewer for a free, demo or paid session by video.
