Ok, after graduated where some people placed in campus placements and some people will go further studies and some are will get refer to their company's and some people will get a employee chance as Third party vendor. Now,coming to job after working hard on one technology for at least 1 year will get bored for every one in IT industry and they don't have a chance to do R & D and don't get a new requirements and don't have a chance to move in to new technology and don't have a chance to put quit for a job because their personal reason. After getting bored on one technology they have moved into another technology their same programming and same requirement but only different syntax's, different programming. Is this happen for every developer, every programmer in IT industry. As I am totally confused which technology I have choose and sometimes I want to quit. According to Booming technologies I choose PHP and than Unix and now the same requirement same work and I am unable to think different in IT industry to move which technology to put challenge. And now I want to move into another technology, I am confused to choose there are infinite technologies in IT industry.Please guide me which technology I have to choose to get complete knowledge. As some one is telling to choose Hadoop technology. Thanks & Regards, Mahesh
