I was invited to the drive. Had 1 round F2F. Interview Process Questions were : 1) Find if a string is rotation of another string ex. abcd , dabc is rotation of abcd 2) Find min distance between two character in a string ex. a x c a e r r a d e min dis between a and e is 1 Interviewer was good . He asked me to describe first approach and then write neat code for both problems. He was not in hurry and gave me sufficient time to think the approach and write code.
