Do you think its possible to get your dream job after you spent more than 8 years doing other type of jobs?

Depends on the company you are willing to work at ...I mean most companies requires a certain number of experience years in a certain field and moving to a totally new job means that you will be treated as a fresh graduate ; and I think most companies will not prefer that ... so the bottom line is if you are planning to change your carrer better do it right now than later if you can
