Pros
Absolutely none. I would recommend ANY other agency over LPI.
Cons
If I could give zero stars, I would. Dishonest, aggressive, and extremely rude. They found out another agency submitted me for a job, and lied to the HR Director the Firm I went for the interview at (submitted by another agency) telling him that they no longer worked with me, yet were calling me daily. I then tried to confront them about their lack of integrity, but of course, they did everything they could to avoid the situation. To make matters worse, they had some of my belongings from a contract position and refused to release them to me. Ultimately, I had to call the police and initiate a small claims dispute for the value to simply retrieve my belongings.
I'm now with another agency who also says they hear countless stories of their lack of integrity, rude behavior, and aggressive attempts to keep you in low paying temp jobs instead of looking for permanent placement. With so many agencies in No. VA, MD and DC, avoid LPI at all costs and go anywhere else!
