Infosys System Engineer interview questions

They asked me about OOPs and os concepts

My interview went on for around half an hour. I had been asked technical questions like what are the advantages of OOPS. Then I was made to write a simple Java program. Then the interviewer asked me about SQL, like what are joins and then he made me implement the logic of joins by making me write different types of queries. At the end he asked me a situation based question. For the HR questions, he only asked me why I want to join Infosys. My interview went pretty well.
