DAY 2: (Interview Rounds)

Round 1 (Technical Interview – 45 min approx.)
The Interview started with his introduction , what his department is , what do they do and so on.

  • Given a link list of 0’s and 1’s sort it so that all the 0’s are at beginning and 1’s at the end. It had to be in-place.
    You cannot swap values only pointers.Order of 0’s and 1’s was to be maintained . I had to write production level code for this with all boundary conditions checked!
  • Given an array of 0’s and 1’s again and a variable k , print the size of the smallest window which contains exact k 0’s .
    • discussion about the best optimised approach .
    • I solved it by storing indexes of all 0’s and calculating min diff b/w every k elements.

Round 2 (Technical Interview – 1 hr approx.)
The interviewer asked me to introduce myself and then my projects.
