You can write a lot of resumes, but you must have priorities. You should clearly distinguish between what you are involved in and what you are responsible for, otherwise the interview will be completely exposed.
Avoid exaggerating yourself and don't be too confident. Self-confidence is definitely there, but it must be buried deep in your heart, and your career is long. Speaking of the key, it can be called talent. In short, talents are made, not just spoken.
Keep your mind down, be modest and don't be arrogant. This will gradually enlarge your narrow mind, and you will lose the motivation to further improve yourself.
