Costain appreciates the time and effort taken when applying for one of our positions. Due to high volume responses, we are unable to provide individual feedback at application phase. We do share individual feedback following an interview. A Disability Confident employer will generally offer an interview to any applicant who discloses a disability and meets the minimum criteria. In certain recruitment situations such as high-volume or peak periods, the number of interviews may be limited.
