Yes, it's normal. State-owned enterprises, financial institutions, large enterprises and foreign enterprises will let you write. It depends on your family background. From your background, you can judge whether it is suitable or your motivation to apply for a job. For example, if you want to go to the bank and your parents are farmers, it is estimated that it will be difficult. It's not that you discriminate against farmers, but that you don't have such a family atmosphere. Some work will be very hard in the early stage. If your parents have a big business background, people may think that you can't bear hardships.
