The nature of my job has prepared me for this position. I have a vast, hands-on experience in warehouse operations. During the past five years I have performed various roles in this environment.

Stock and admin clerk position appears to be an exciting and challenging role, that will allow me to utilize skills and experience I already possess and make an effective contribution to the business while continuing to gain further skills and knowledge.
As for the shift preference, I am ready to either stay on my current shift, or switch to day or afternoon shift, should the need arise.
