Interview Process   |   Interview Puzzles / Aptitude
Organization : Infogain
Position : Software Developer
I gave the interview in October end and it comprise of three different rounds in total. I am mentioning the details below:

First Round: Written Round
The total time given for this round was 70 minutes. There were three different sections in this written test:
  • 10 English Questions

  • 30 Questions of Quant

  • 20 technical questions

  • The English questions were easy for me and the most difficult ones were the technical questions. It consisted of some tricky c/c++ questions and sql related questions. Watch out for the time as you may run short of that.

    Second Round: HR Interview
    The HR interview round consisted of two different parts.

    ===Casual HR Questions===
  • A brief information about yourself

  • Your strength and weakness

  • What do you do to overcome your weakness?

  • Tell me your thoughts about Infogain

  • Where do you see yourself after 5-6 years

  • ===Tehnical Questions and Aptitude Questions====
  • A reasoning aptitude problem

  • Difference between struts1 and struts2

  • Sorting arrays

  • Pattern

  • Any five OS

  • Third Round: Technical Round
    This was the most difficult round and I had a hard time answering the questions. I am mentioning some of the questions I remember:
  • Program to find duplicate number from array in minimum time complexity.

  • String Handling

  • WAP to show polymorphism

  • Overall, the interview was not too hard but it was not easy either. You must prepare well as the technical round can be a difficult one to crack.

    Thanks Anmol for sharing the details of your interview.

    Maths Magic Riddle

    I can prove why 1 = 2

    Step1. Lets say y = x
    Step2. Multiply through by x xy = x2
    Step3. Subtract y2 from each side xy - y2 = x2 - y2
    Step4. Factor each side y(x-y) = (x+y)(x-y)
    Step5. Divide both sides by (x-y) y = x+y
    Step6. Divide both sides by y y/y = x/y + y/y
    Step7. And so... 1 = x/y + 1
    Step8. Since x=y, x/y = 1 1 = 1 + 1
    Step9. And so... 1 = 2

    How is this possible ?

    A couple had to take shelter in a hotel for they could not proceed their journey in the rain. Having nothing to do at all, they started playing cards. Suddenly there was a short circuit and the lights went off. The husband inverted the position of 15 cards in the deck (52 cards normal deck) and shuffled the deck.

    Now he asked his wife to divide the deck into two different piles which may not be equal but both of them should have equal number of cards facing up. There was no source of light in the room and the wife was unable to see the cards.

    For a certain amount of time, she thought and then divided the cards in two piles. To the husband’s astonishment, both of the piles had equal number of cards facing up.
