each and every thing from c/c++ (because it was mentioned in my cv). believe me each and every single thing. i would recommend you should know all basics of the skills mentioned in your resume....from 'what a single variable is' to 'what is pointer' to data structures...to the logic for creating any activity on web page (remember, you would be asked everything from resume) The interviewer didn't asked me to write the programs....but asked me to tell the logic only. Questions like reversing a linked list...making pattern..virtual functions....how can pointer save memory...each and every thing
