LTIMindtree interview questions and answers

Technical round

  1. 1.What are time complexity and Big-O?

    What they're checking
    Whether you understand code efficiency.
    How to answer
    A measure of how much slower code gets as the input grows. A loop = O(n), a nested loop = O(n²), binary search = O(log n).

  2. 2.What is hashing?

    What they're checking
    Data structures.
    How to answer
    Turning a key into an index with a function so you can find it quickly - like a HashMap. Also explain what a collision is and how it is handled.

  3. 3.Explain the MVC architecture.

    What they're checking
    Software design basics.
    How to answer
    Model (data), View (what the user sees), Controller (the logic between them). Give the example of a web app.

  4. 4.What is Docker / a container?

    What they're checking
    Awareness of modern deployment.
    How to answer
    An app and everything it needs in one package - it runs the same way on every machine.

  5. 5.What is the difference between DELETE, TRUNCATE and DROP in SQL?

    What they're checking
    SQL basics.
    How to answer
    DELETE = remove selected rows (can be rolled back), TRUNCATE = remove all rows but keep the table, DROP = remove the whole table.

HR round

  1. 6.Are you ready for rotational shifts and relocation?

    What they're checking
    Common in service roles.
    How to answer
    An honest, clear answer. If you are ready, say so without hesitation; if there is a genuine problem, explain it politely.

  2. 7.What was your contribution to the project?

    What they're checking
    Hands-on work.
    How to answer
    Be specific - which module, which problem you solved, what you learned.

  3. 8.Why LTIMindtree?

    What they're checking
    Research.
    How to answer
    Link a piece of the company's work or a technology area to your goal.

More technical questions

  1. 9.How does merge sort work?

    What they're checking
    Divide and conquer.
    How to answer
    Keep halving the array, build small sorted pieces, then merge them. O(n log n) in every case, but it needs extra space.

  2. 10.What is the difference between PUT and POST in HTTP?

    What they're checking
    API basics.
    How to answer
    POST creates a new resource (sending it twice can create two). PUT replaces/updates a resource (sending it twice gives the same result - idempotent).

  3. 11.What is the difference between merge and rebase in Git?

    What they're checking
    Team workflow.
    How to answer
    Merge joins both histories with a merge commit. Rebase replays your commits on a new base, keeping the history straight.

  4. 12.What is a view in SQL?

    What they're checking
    DBMS.
    How to answer
    A saved query that looks like a table - used to simplify complex queries and to control access.
