Work experience: start and end date, company, position, responsibilities, achievements; 4. Project experience: start and end dates, project name, project content and results, responsibilities and tools used; 5. Awards received; 6. Training received; 7. Personal Profile; 8. Interests and Hobbies Note: The project experience must be prepared clearly, the interview is to ask!
