Empower Integrated Solutions (P) Ltd. Java Software Developer Hadoop interview questions

Two Tests: 1) Technical Test- Java- Very Simple questions. 2) Logical Test- Simple but time consuming. After clearing technical and logical tests, HR told me to wait for Technical interview with VP. It took almost an hour to start as VP was busy in some phone call.Interview lasted for an hour and was very good experience. Asked me some tough technical questions and about previous work done. Then surprisingly gave me a logical query and asked me to solve it by using multi-threading. Asked me about my expectations and future plan. after finishing the interview VP told me that he was satisfied and will send you mail for scheduling skype interview with another senior person. waiting for that mail !
