There are lots of different careers in HR. You can stay general and do all the different parts or you can specialize in a certain area. Larger companies have bigger HR departments. However, that depends what you count as HR. Some companies include payroll but in others it is a part of finance. We have 2 people in the HR department for a company of 300 people. The most important thing is getting your foot in the door. You normally have to start in a clerk type job and then work your way up. Eduction is always a bonus but experience is more important.
