Interview experience was very good, I was hired through campus and interview complexity was above average. there were 4 round of interviews and was very fun and learning experience. They take written exam and trust me it is not easy to crack. Toughest I have given so far.

The interviewer first asked me to introduce myself. Then he asked some basic concepts from java like polymorphism, static and dynamic polymorphism, overloading and overriding. After that, he showed me a java code based on multilevel inheritance and asked me to find the output which was easy. Then, he started asking me some questions from data structures and algorithms like what is the difference between hashmap and hashset. Can they contain duplicate elements? keys concepts in hashmap and stuff like that. Again, he gave me a question based on DSA. Although it was easy I couldnt do it but i tried to explain my approach. Then, he gave me two questions from SQL where i have to write queries. The first one was easy so I did. The second one was bit hard. So thats it I think
