Costain appreciate the time and effort taken when applying for one of our positions but, due to the high volume of responses, we are unable to provide individual feedback on candidates at application phase.

We do share individual feedback following an interview .

A Disability Confident employer will generally offer an interview to any applicant that disclose they have a disability and meets the minimum criteria for the job as defined by the employer.

It is important to note that in certain recruitment situations such as high-volume, seasonal and high-peak times, the employer may wish to limit the overall numbers of interviews offered to both disabled people and non-disabled people.
