Shell Programmer interview questions

Took 2 online assessments and submitted my resume. Took another few months before I was scheduled for a phone interview. I passed the phone interview and was then invited to a Shell Recruitment Day in Houston, TX. You are asked to complete an eTray assessment which consists of a multiple choice section and a written section. Then, you have an interview about the eTray which you took. After that, you work on a group to solve a problem. You have a competency based interview, then a case study to complete. Challenging interview on all accounts.
