I think another piece is asking the right questions when interviewing. You need to consider all of the compensation being offered, not just salary.do they offer health care and paid time off? Do they support your continued education or APTA membership? Do they provide free, safe parking? What are the hours like? What is your patient case load and productivity expectation? Do they have a mentorship for new grads? can you spend time observing the other staff and how the clinic operates? This will allow you to get a sense of the overall workplace environment. There are a lot of things to consider when finding, a "good job." It will also be different for every PT. It's all about finding the right fit for you.
The best way to ensure you get the "best" PT job is to build up your resume starting now. Volunteer at Rehab facilities, hospitals and outpatient clinics. As you do all this, remember to include it in your resume. When you are ready for college, you will have a leg up when the administrators are picking who they want to be a part of their PT program. You'll never know what the right job is for you until you have worked in different areas of the field. I don't think there is such as thing as the "best" job, which is why I put it in quotations. It's more along the lines of finding the "right" job for you. Remember, everyone has different interests so whats right for you may not necessarily be right for another Physical therapist.
Hope this helps!
