1. Tell me about yourself. 2. OOPS concepts and their practical implementation examples from real life. 3. SQL queries 4.simple constructor overloading code 5.pseudo code to implement 2-way lift in a 4-floor building (this i felt really difficult to code and explain to him because he gave only 5 mins for that) Dont worry about data structures and algorithms because they will go maximum to linked list and they probably hate algorithms or don't know any! Best of luck!
