Dear Sir or Madam,
I feel that I have all the qualities required for the task proposed.
First, I am personally using Linkedin so I know exactly how it works and how to use it properly.
Secondly, I am currently working in an Office,so I am particularly familiar with Excel and I am able to work quickly on a computer.
Then, I am serious and perfectionist, so I will do my best to successfully execute this mission.
Finally, I have a lot of spare time so I will be able to finish this task really quickly.
Thanks, and I hope to meet all your requirements.
Best regards,
Chloe
