New figures have shown that the number of people unemployed in the UK rose by 53,000 to 2.51 million during the three months of 2010, the highest level since December 1994.
However, the total number of people claiming unemployment benefit fell in April by 27,100 to 1.52 million - a sharper fall than expected.
According to the Office of National Statistics, the rate of unemployment remained at 8%.
John Philpott of the Chartered Institute of Personnel and Development said the latest data underlined how tough a challenge the new coalition government faced and there was nothing to suggest the UK would get a return to anything approaching full employment anytime soon.
The latest figures also suggest that job seekers will continue to find it difficult to find work in the months ahead.
As a result they will need to make sure they present the best possible impression if invited to an interview, and familiarise themselves with popular recruitment techniques such as psychometric testing.
Employers will also face challenges ahead, finding it harder to find the right candidate from an increasing number of applications for a diminishing number of vacancies.
Again psychometric testing, particularly on-line psychometric tests, can help to filter out unsuitable candidates at the earliest stage of the recruitment process.
