   I have received the call from the consultancy and appeared for the interview on a week day. I was getting interview for their RnD division so consultancy has told me to prepare deeply on Core java concept,Spring and database.

Round 1 

It was a written round consist of technical and logical questions, technical questions were 30 MCQ and 2 coding questions. MCQ were kind of similar types of OCJP questions checking the core java concepts deeply and in coding part there was 2 questions, one was a simple question on java programming and other one was to write SQL queries  based on the given tables.

Round 2

It was a F2F technical round and the interviewer was looking technically too sound.Questions were from the following topics:

•         Maven configurations and how create maven project , how does it working ?

•         Restful web services basics, like how to do CRUD operations, what all are the annotations that are available in resteasy
•         Final question was to write program, Q: There is a internet cafe having N computers if somebody comes to the cafe any of of the computer gets allocated to that guy and he enters his name in the register and when the next guy comes he will enter his name then check for vacant computer if it is available he will use the computer, if it is not available he will enter his name again in the register and will leave. Once the user finishes the use then also he will enter his name in the register and will leave.Say 2 computers are there A came and enter his name , then B comes enter his name then C comes enters his name but both the computers are in use so C will again enters his name in the register and will go back without using. Now B leaves the computer then he will enter his name in the register. Now D comes enter his name and he gets the system.Now the register entries will looks like ABCCBD.So the question is if you are given a string denotes the register entries then find the number of customers has returned without getting a system. in the above case 1.      [Used HashMap and few conditions to get the answer]
