Over the years, I have acquired relevant skills and experience, which I shall bring to your organization.
I have also worked tirelessly on my communication abilities and teamwork skills, which I will put to use in my future career, which would be in your organization if I am selected for the position.
I have given my 100% effort in my past companies, and this has enabled me to recognize my capabilities and limitations.
If I channelize them further, they will bring fruitful results to me and also to your esteemed organization.
