Indeed Software Developer/Engineer interview questions

on campus recruit. Regular phone screen, onsite interview

On campus interview. Instead of phone round, we had it in our campus. 2 rounds. each half an hour. Same questions from previous indeed itnerivews.But one question was new. 1) If you are getting a paragraph of string of text as input to a function, seggregate words, and find first duplicate word in the paragrpah and return it. 2) In excel sheet, the top most row. has A, B, C...Z, AA, AB....AZ,,, BA, BB...BZ... Consider A as 1, B as 2....Z as 26, then AA as 27 , AB as 28..... The input for function would be an int and find its equivalent text. hint by inteviewee: hash mpa, one divide, one module, StringBuilder with append function. Let me post further questions If I get call for other interviews.
