how to explain why a company shouldh hire you code example

Example 1: why we should hire you

I feel that this position ideally fits my work experience,
skills and qualifications.
That’s why, I will be able to make significant contribution to your company
as well as perform my potential.
I would like to work for a company where i can make a real difference.
I think I would be a perfect candidate and compatible fit for this position.
I am a very good communicator, extremely self-motivated And
I am detail oriented especially for deadlines.

Example 2: what do you do if I hire you

What do you do if I hire you?
In first week, you know, I will get done all the
paper works, getting the tools and necessary 
access to the project, take may be an on board
training for warm up quickly.
Then I will have to learn the company culture.
I have to learn also more about projects,
application and my teammates.
I think, understanding what the application
is doing is very important if I want to be more productive.
So, it will take 1-2 weeks to be ready to 
write my first test cases. I think a sprint 
is enough to figure out most of the thing about
application and working culture in the company.
