Preguntas de entrevista para el cargo de Java Developer en EPPS Infotech

I got the mail from Epps and called for interview on next day in the second half. I was there at 2 pm in the afternoon I reported to reception and I had to wait for 1 hr for first pre hr interview, she asked some basic regular questions like Tell me about yourself? Tell me about your family? Your technical expertise and experience on frameworks and then she told me to wait for some time for technical round. I had to wait again more than 1 hour for next round. Then some technical person had taken my second round asked basic questions on core Java? 1) Explain OOPs concept? 2) In how many ways we can create the thread? 3)How to override hashcode and equals method? 4) what is upper bound and lower bound in java? 5)What is Transaction in Java? 6)How to write our own annotations? and many more. and then he said hr will call you back and they will never call you? Even if you send them the follow-up mail they never give the response to your mail. So its better don't go for Epps infotech and save your valuable time
