I was referred by a current employee. It's all about networking. I was working for a city entity and got to know consultants through my work. One of the City employees who knew me moved over to AECOM and got me into contact with a project manager. The day of our one on one, I dressed professionally in a suit, which was appropriate. I showed up 30 minutes early. I brought a sample of my work and my resume, even though they did not ask me for it. I was prepared with pertinent examples of job experience. I recommend fully researching the position and getting into contact with an alumnus or someone else on the inside.
