Should I use the read sentence or blue sentence?
I am recognized for making valuable contributions to the company.
My contributions to the company are highly recognized.
For example, I developed a product which is very attractive for young people, and I made a website for the company.
I would use something like "I have made important contributions to the company, such as developing a very popular product for young people, and building a website for the company. The value of these contributions has been fully recognised by my managers."
Remember that you might have to go into more detail about the product and the website, and that you may be asked to provide evidence that the company recognised your efforts in these areas.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
