These guys work in cellar/basement and the person who conducts the process of interview asks you to come for two days to know about work without giving any affirmation from his side and doesn't discuss anything about the CTC even after two days of work and sends you back. It's just a micro management. I think its their way of completing pending work at free of cost. It's just a waste of time and money to attend for an interview at Visapro.
