Deloitte Software Engineer interview questions

Overall just usual java questions and a small problem. Singleton, sql questions, interface vs abstract, lambdas, java memory. We had a talk about Deloitte and then my experience. He was very open and we had a nice conversation. I was left with a good impression.

there were three rounds. aptitude, technical and HR all were pretty easy. Apt they tested basic math and reasoning. technical also basic programming questions, HR round they just discussed package. I got the job
