Vacation work leading to a graduate position
A number of employers use vacation work as one of their graduate recruitment strategies. Employing a student during all or part of the summer vacation provides an employer with some valuable insights into your skills, how well you fit in to the organisation and what sort of future potential you might have. It's much more reliable than a 45 minute interview and you also get some very valuable practical experience that is closely related to your course of study.
