The first interview might be a screening interview with a member of Human Resources (HR) to assess your suitability to join the company. This interview might only focus on HR-type questions that attempt to determine your career goals, your personality, why you have left one company for another, etc.
It really helps if you can find out ahead of time exactly who you're meeting with during the first interview to get a sense as to what will actually take place during the interview.
The point is that ideally you will find out ahead of time exactly how the interview process is structured so that you can prepare for it and so that you can avoid any unexpected surprises.
In any event, the goal of the first interview from your perspective is to answer all questions concisely and as well as possible, to gain more information about the company and the job and of course to proceed to the next step in the process if it's a job you are still interested in.
good luck
