There was a difficult string question which I need to write on paper

.One of them started by saying "tell me something about yourself " then explain your project (reference from intro)followed by question Then asked by linux grep command followed by sql query(top n) then i was asked to write palindrome check function without string reversal then asked about circular linked list(how to check if its circular) then other interview asked "why should we hire u" and ended interview by asking if i had any question for them
