BANGALORE, May 22 (Reuters) - India-based back-office firm WNS (Holdings) Ltd (WNS.N: Quote, Profile, Research) aims for revenue growth of 30 percent to 35 percent per year on a long-term basis as it sees expansion opportunities in Europe and North America despite worries of a U.S. recession, its chief executive said.

"The industry is capable of growing 25 percent to 30 percent a year and our aspiration is to grow faster than the industry," CEO Neeraj Bhargava said in a phone interview.

However, he said the long-term growth rate was an aspirational number, not an outlook.

The company's revenue grew 32 percent last year and it has forecast a growth of 28 percent to 30 percent this year.
