Besides, you are what I think, I think. . . Something like that. With so many job seekers, why should employers believe in your self-belief? At work, it's not what you think, as long as you have some skills. Besides, there are many people who study program development, and so will those who know you, perhaps even worse than you. In addition, do you know the workflow of the position you are applying for? Do you know how this position should cooperate with colleagues in other departments? There will be many such situations.
I suggest you, first of all, be modest and confident. You are a fresh graduate with less experience than your predecessors, so you should be modest, but you should have the determination to be competent for the future work in the shortest time and keep up with the pace of the company, so you should be confident. In addition, what fresh graduates need most is work experience, so don't take salary so seriously at first. Never fake it. No formal company is willing to hire a dishonest employee.
What position do you value? You can call HR directly and ask him about the recruitment and specific requirements of this position to show your sincerity, so I hope it will be even bigger. I am an employee of 5 1. I wish you an early job.
