Understanding your personality and interests will help you identify what type of legal career will be the best fit.
Finding lawyers who specialize in areas you are interested in can provide contacts who can give first-hand insight on the type of work you are considering. Researching potential future employers can help you decide what jobs to apply for and be more confident during an interview.
It is always a good idea to talk to professionals who work in the practice area or legal sector that you are considering. Researching practice areas of interest and following topics in the field is also a good way to get a sense of the type of work you may encounter and to prepare yourself for interviews.
