1. The second interview is similar to the first interview but with executives. It involves around you being loyal to the company. You have to demonstrate not just your ambitions of flying but what you can bring to the company.
2. The motivation letters are used by REX to gauge whether you fit their selection criteria through written language. These letters are usually very personal.
