Virtusa interview questions and answers

Technical round

  1. 1.What is the difference between UNION and UNION ALL in SQL?

    What they're checking
    SQL basics.
    How to answer
    UNION removes duplicates (so it is slightly slower); UNION ALL keeps all rows. Both need the same number and type of columns.

  2. 2.What is the difference between checked and unchecked exceptions?

    What they're checking
    Understanding of Java.
    How to answer
    Checked - must be handled at compile time (like IOException). Unchecked - at runtime (like NullPointerException), handling not required.

  3. 3.Name the types of inheritance in Java.

    What they're checking
    OOP.
    How to answer
    Single, multilevel, hierarchical - with classes. Multiple inheritance comes through interfaces, not classes.

  4. 4.What do the HTTP status codes 404 and 500 mean?

    What they're checking
    Web basics.
    How to answer
    404 - the page/resource wasn't found (client side). 500 - an error in the server (server side).

  5. 5.Find the height of a binary tree.

    What they're checking
    Recursion.
    How to answer
    Height = 1 + max(left height, right height); an empty tree = 0 (or -1 - state your definition).

Code snippets and coding

  1. 6.Find the error in the given code.

    What they're checking
    Error-detection questions have been reported in the test.
    How to answer
    Check syntax (semicolons, brackets), types, loop boundaries and null checks - in that order.

  2. 7.What is the output of this code?

    What they're checking
    The skill of reading code.
    How to answer
    Write each variable's value on paper line by line; don't guess.

  3. 8.Count the vowels in a string.

    What they're checking
    Basic coding.
    How to answer
    Lowercase each character and check whether it is in 'aeiou'.

HR

  1. 9.Why Virtusa?

    What they're checking
    Research.
    How to answer
    Link the company's digital engineering work to your goal.

  2. 10.Can you move to any Virtusa office?

    What they're checking
    Practical fit.
    How to answer
    An honest answer.

  3. 11.What is your career goal?

    What they're checking
    Direction.
    How to answer
    Becoming an expert in a technology and taking on responsibility - realistic and clear.

More questions

  1. 12.How does a HashSet prevent duplicates in Java?

    What they're checking
    Depth in collections.
    How to answer
    It uses a HashMap inside - the element becomes a key; hashCode and equals check whether it is already there.

  2. 13.A website is slow - what would you check first?

    What they're checking
    Debugging thinking.
    How to answer
    The browser's network tab (which request is slow), server logs, database queries, and large images/files.
