I had the worst work experience with Sierra Solutions clean and simple. The company is nothing but a scam. When they hire you, they don't ask for and proof of I.D or Social, They fired me for no damn reason. Working there, i noticed the employees were all drug addicts and are felonies who have nothing better to do but scam people. Nothing they told me made sense. I always had money missing and one of them stole my HTC one phone which is a 600 dollar phone. Dont work or buy anything from these guys, they are so unprofessional.
