1 round: question of array, string manupulation,sql queries.
Second round: create a deadlock situation, write palindrome with all possible conditions, c++ all normal questions, Design pattern, factory and builder pattern difference.
Third round : singleton design pattern, finding missing number in unsorted( duplicate number available) from int array, optimize it, complexity. Give questions in inheritance and polymorphism. Ask to implement Design for shapes, circle and picture(collection of shapes)
