Cognizant Advanced Java Developer interview questions

Interview started with basic questions like Oops concepts , Overloading vs Overriding , Constructor Overloading. Few conditions were given under Constructor overloading and they asked for the output. Questions like Errors vs Exceptions , Garbage collection, Hashmap , Inheritance examples were asked. Then I was asked to write the programs to check if a string is a palindrome , Sort the array , break the sentence into words and printing them. It was actually a good experience.

First round was a 3 hours test in which they asked mcq's on html,java, pseudo codes and SQL queries and 5-6 coding questions. Second round was a technical interview in which the interviewer asked me about oops concepts, some java concepts, SQL part and gave some queries and coding questions to solve . Then the last round was hr round in which they asked only about the documents it was kind of document verification round.
