How about taking the civil service exam at the age of 30? Will it be difficult?

Whether it is difficult or not has nothing to do with age, as long as you are within the age range of civil servant recruitment. As long as you have the corresponding knowledge reserves, passed the examination interview and written examination, there is no problem in political examination and physical examination, and the comprehensive score is within the admission range, there is no reason for the recruitment department not to admit you. Older people have the advantage of being older. Older people are relatively mature and have rich experience in dealing with and solving problems. I met a (municipal authority) who was admitted to the civil service at the age of 35. Because of his outstanding performance in all aspects, he is particularly diligent, capable and efficient, and has made rapid progress in the organs. In the words of colleagues, his progress was "one step behind" and he became the deputy director of the department around 10. You are only 30 years old, and I think you are very moderate. As long as you have the conditions, believe in yourself and get ready quickly, you will succeed!
