A technical interview is a type of interview that typically features questions that are specific to the role you have applied for. Technical interviews are generally used to assess candidates for technical or specialist graduate job positions (such as jobs in IT, Engineering and Science) rather than general graduate schemes.
In a technical interview candidates are likely to be asked questions that:
relate to specific knowledge about the company's technical activities;
relate to understanding the technical work required to be completed as part of the job applied for;
relate to work completed as part of a degree course (if this relates to the job applied for);
equire candidates to solve actual technical prolems that they would be likely to face if employed.
