After carefully reading few job responsibilities and qualifications for this position, I come up with few
sentences to prove that I am the right potential candidate. My educational background and work experience at
DC Water allow me to understand the water and wastewater treatment utilities further. During my college time,
I have participated in a project "simulation design a wastewater treatment plant with AutoCAD, " which proves
that I am familiar with the AutoCAD and can use AutoCAD and SUMO to do designing work. As a research
assistant, I know how to manage different projects at the same time and write technical reports. What's more, I
have passed the Fundamental of Engineering Exam last December, which makes me more qualified for this
position.
