Hello Costco,
My name is Marvin and I am writing because I am interested in the membership service position that you have open. I believe that I have the skills and qualities that you are looking for in an employee and I would love to have the opportunity to show you what I can do.
I am a people pleaser and I enjoy helping others. I speak Spanish, English, and Portuguese fluently and I am confident that I can provide excellent customer service to your members. I am looking for a fulltime role and I believe that this position at Costco would be a perfect fit for me.
I am excited to learn more about the company and to see what Costco has to offer. I am confident that I can be an asset to your team and I look forward to hearing from you soon.
