Degree programs actually called "HR manager" are rare, so people usually enter the field through a bachelor's degree in management, human resource management, psychology or economics. Many universities in Kazakhstan offer these programs, and they usually take four years. Management and economics often require math and geography on the UNT, but check the exact requirements for your program.
Many people start as an HR assistant or recruiter while still studying and grow inside the company. Courses in recruiting, labor law and HR analytics help a lot, as does English if you want to work for an international company. In this field, experience and an understanding of business are valued as much as a diploma.
