Candidates that do not pass the interview but have demonstrated an acceptable standard may be considered for similar roles at a lower grade.

A reserve list will be held for a period of 12 months, from which further appointments can be made.

Please note that this role requires SC clearance, which would normally need 5 years’ UK residency in the past 5 years. This is not an absolute requirement, but supplementary checks may be needed where individuals have not lived in the UK for that period. This may mean your security clearance (and therefore your appointment) will take longer or, in some cases, not be possible.

For meaningful checks to be carried out, you will need to have lived in the UK for a sufficient period of time, to enable appropriate checks to be carried out and produce a result which provides the required level of assurance. Whilst a lack of UK residency in itself is not necessarily a bar to a security clearance, and expectation of UK residency may range from 3 to 5 years. Failure to meet the residency requirements needed for the role may result in the withdrawal of provisional jobs offers.

DSIT cannot offer Visa sponsorship to candidates through this campaign. DSIT holds a Visa sponsorship licence but this can only be used for certain roles and this campaign does not qualify.

Feedback will only be provided if you attend an interview or assessment.
