In fact, both the ability and the diploma are essential, and the ability is necessary. This is basically not questioned. The following focuses on why the diploma is necessary.
When you are looking for a job interview, your academic qualifications are a stepping stone. You have a high education and a good school. Just go knocking on the door, but if you don't have a degree, you have to take your work to the door, and you can't open it. You still have to look at your work too hard, but when you enter the interview door, you must rely on your actual skills.
You may say that high academic qualifications are not necessarily capable. Yes, you know the problem. You think the interviewer is a fool. I don't understand. And why, when many large companies recruit, must they also limit the school to a prestigious university? Is it a master's degree or a doctor's degree?
However, in the end, the ability is the most important. You don't look at your education when you enter a particular company. But if you have a high degree of education and a prestigious school, you can basically judge where your ability will go well. Education is also an auxiliary proof of ability. From a probabilistic point of view, a person with a high degree of education and a famous school is not qualified for a specific job. There is no need to talk about people with low education in ordinary schools.
Therefore, the academic school is still critical. Otherwise, if a person has the ability and has no education, who can not even have bricks, how can he open the door to employment? Others have no chance to know your ability. It is easy to become a "grass hero" buried. Tthese may beare the rules of the game for finding a job. If you understand the rules, you will be more relaxed. If you don't follow the rules and can't get good work, you have to prepare yourself to be rejected. Don't talk about social reality because society is such a reality.
For 90% of the students, what ability do you have? I guess you can't say it; maybe the only thing that can prove the ability is the academic qualifications and academic achievements. So, when you don't have a high diploma, why don't you consider a degree for yourself online?
