First: I believe you will be lucky enough to consider my application, and I assure you that I will make every effort to live up to your trust in me.
If your company can consider my job application, I can guarantee that I will do my best to serve your company and trust you.
Number two: I want to make a change now? Because I don't think I can make greater progress in my current job, I think my training should enable me to get a better and more responsible position, which seems impossible in my current job.
I am confident that with my ability and training, I should get more rewards and get a higher position, but as far as my current job is concerned, I won't have much future.
Third: I would like to promise you that if I succeed, I will try my best to give you everything? Satisfaction.
If you accept me, I will try my best to satisfy you.
The fourth type: I believe you will consider my application and hope to hear your consent.
Please consider my application and let me know by letter.
