I received an offer letter without even a telephonic conversation... they simply gave the offer letter once they asked to fill up a small form concerning my details .... after the first mail , i googled but the company's name was nowhere to be found ..evn the address was not there on googlemap... then i asked them about it and the very next day a whole new website poped up .. strange!!!! ... In short its a fraud... beware .,... again the name is Voltasol Nacional S.A.
