Typical graduate candidates are interviewed on campus and, pending qualifications, flown to Houston to participate in a two day interview process called Shell Recruitment Days (SRD). Each SRD consists of 8 to 10 people, typically of different college majors and from different universities. The SRD process is mainly looking to see if a candidate meets the personable and team working skills requirements that Shell highly seeks in its employees. Critical thinking and business prowess are assessed, albeit secondarily. Technical knowledge, however, is not assessed; Shell recruits from a list of universities known for producing candidates with the required job skills to work in the business.
