I Am A Junior, And I Havent Really Had An Office Internship…but I Had Summer Internship Once At Disney.?

Would I get a good job after school,if i hadnt had a any work experience? I have a year to go. What shd I do, if I am graduating a year and a half?? Shd I start looking now for a job for after graduation? If I am in my 3rd year can I look for a internship, for the summer during my 4th??
