I've noticed that not everyone has a degree in HR. In my case I have a BA in Psychology and Economics and a MSc in work and organizational Psychology. My Masters required me to obtain an internship in HR which gave me greater insight and experience in HR. Learning theories and practices is great but the experiences is what will allow you to grow. When I started to apply, I noticed it very competitive (this varies per location) so having some experience is ALWAYS helpful. Start with an internship and then apply to be a coordinator.
HR has many fields-- recruiting, operations, hr systems, compensation, learning and development, diversity and inclusion, business partners. Starting with an internship or coordinator position will allow you to see everything without getting involved in just one section of HR. You will then decide what you like best. If you are a people person, organized and on top of everything-- you will excel and keep growing in the field.
If you have any other questions, don't hesitate to ask.
