My attention was immediately drawn to the advert on LinkedIn, where it was stated that your reputable company is looking for an office assistant. The profile you outlined fits me very well as I will further explain.
Solar being a form of clean and green energy and an alternative to the depleting fossil fuel has come to stay. With my experience as a member of a research group on renewable in my undergraduate days, and with two articles published, your organization would be an environment I want to be in.

I am a self motivated young lady, who is always cheerful, a great team player and a very fast learner.Having great knowledge of an assistant from my past work experience, I know am best fit for the job.

I look forward to seeing at an interview session.

Thank you.
