Flipkart hiring process

  1. Machine coding

    Building a working program from a problem statement - about 1.5 hours. Code quality, edge cases and being bug-free are what count.

  2. Problem solving (DSA)

    A DSA round of about an hour - arrays, graphs, trees, DP, heaps.

  3. Hiring manager round

    Projects, communication and culture fit - sometimes technical too.

Flipkart interview questions and answers

Machine coding

  1. 1.Build an expense-sharing app like Splitwise.

    What they're checking
    Working code, OOP design and extensibility.
    How to answer
    Classes: User, Expense, Split (equal/exact/percent). Balances in a map. Get the core flow working first, then extra features. Show it with tests or a demo main().

  2. 2.Design a shopping cart with discounts.

    What they're checking
    Clean code that is easy to change.
    How to answer
    Put each discount in its own strategy class (percent, flat, buy-one-get-one) so a new discount can be added without changing old code.

Problem solving (DSA)

  1. 3.Find the next greater element for every element.

    What they're checking
    The stack pattern.
    How to answer
    Go from right to left, keeping larger elements on a stack. O(n).

  2. 4.Sliding window maximum.

    What they're checking
    Using a deque.
    How to answer
    Keep indices in a deque, drop smaller elements from the back and out-of-window ones from the front. O(n).

  3. 5.Rotten oranges: in how many minutes will all of them rot?

    What they're checking
    Multi-source BFS.
    How to answer
    Start BFS from all rotten oranges at once; each level = one minute. If any fresh ones remain, -1.

Hiring manager

  1. 6.Give a deep dive into your best project.

    What they're checking
    Ownership and understanding.
    How to answer
    The problem, the design choices and their trade-offs, your part, and what you would do differently if you built it again.

  2. 7.Why Flipkart?

    What they're checking
    Motivation.
    How to answer
    Large-scale e-commerce problems - say what genuinely appeals to you.

More questions

  1. 8.Machine coding: build an elevator system.

    What they're checking
    Designing state and scheduling.
    How to answer
    Elevator (current floor, direction, requests) and a Controller that assigns requests. One elevator first, then several.

  2. 9.Minimum cost to connect ropes.

    What they're checking
    A greedy heap problem.
    How to answer
    Put all lengths in a min-heap; take the two smallest, join them, add the cost, put the result back.

  3. 10.Word search in a grid.

    What they're checking
    Backtracking.
    How to answer
    DFS from each cell, mark visited, and backtrack when the next letter doesn't match.

  4. 11.What do you do when the deadline and code quality conflict?

    What they're checking
    Hiring manager thinking.
    How to answer
    Prioritise what is essential, write down any shortcut you take, and plan to fix it later.

One more question

  1. 12.Traffic grows ten times during a sale like Big Billion Days - how do you prepare?

    What they're checking
    Thinking about scale.
    How to answer
    Load testing, caching, auto-scaling, queueing orders, and prioritising essential features - switching off the rest gracefully.
