My job and my career I studied accountant in the college, so I worked as an accountant after graduation for 7 years. It was my career and my job. But for financial reasons I changed my job to anther one in the IT field and after 3 years in that new job I think I will not work as an accountant again even if I have a better offer. So I think it means that I didn't just changed my job but I changed my career.
