Ive been there. Being rejected not only once but multiple times. Sometimes it really made me feel down and worthless but you know, there are a lot of companies out there that will know your worth and treat you as their valuable asset even if they are just a small company. It is really hard being rejected on your dream job and it will really take some time to completely shrug it off but remember that you must not forget who you really are and why at the first place you want and thrive to learn to code. You don't have to change yourself just to please or meet the standards of that big company. You just have to be you and continue on what you are doing. Dont give up! Eventually, you will get your big break in your chosen career.
