{ id = 1, name = PQR, employeeCount = 3430,
projectCount = 220, address1 = add1@, address2 = add2 }
{ id = 3, name = MNO, employeeCount = 26790,
projectCount = 670, address1 = add111, address2 = add222 }
Where in clause with company names
{ id = 1, name = PQR, employeeCount = 3430,
projectCount = 220, address1 = add1@, address2 = add2 }
{ id = 2, name = ABC, employeeCount = 23430,
projectCount = 160, address1 = add11, address2 = add22 }
