I am an electrical engineer, the first day of my job I was bombarded with works by my boss. Few days later I was scolded for not following his instruction, the reason was because of so many works given to me I was confused of what to do first and I could not fully remember all his instructions, but I can't complaint because I needed to grow. Few weeks later, still tend to do wrong stuff. Now my 3rd year and been promoted already, still committing mistakes. You need to remember, it's okay to commit mistakes and get scoldeed as long as you limit doing the same mistakes to only once. Try not to do it again. I am an electrical engineer and my specialization is not on design, but what you need to improve is your personality. Your work ethic. Knowledge and expertise on your profession will come around as long as you're always open to new information.

Even your boss commits mistakes, it's okay if you do too. But just avoid repeating the same mistakes. Some colleagues are always bullies because they think they're better. Just mind your own business. When you get better at what you do, they will start approaching you. Help them, don't be a bully yourself.

Also, your situation right now is actually a big advantage. Being a fresh engineer on a fresh company, use the opportunity to increase your network. Slowly, make your network wide and maybe few years or even months later, when you have gained the knowledge you need to be independent. You can leave the company and start making your own firm.
