If ur talking of the line trail involved in the oil and gas,then from the much i know,they are quite good.dont really know about their interview and all but i know the company is doing well.they are involved in buying and selling of AGO,DPK and PMS at various depots.most times they buy in very large quantities and then sell in bulk to other companies.If ur talking about another line trail,then i dont know.All the best......
