The lecturer advises that in a CV, one should emphasize their special skills and hobbies to give employers a sense of their personality. Relevant experiences both in and outside of work, such as languages spoken or voluntary activities, should be mentioned. A CV should be tailored specifically for each job application rather than using the same format repeatedly. It is important to proofread the CV carefully for spelling and grammatical mistakes, as those with the best-presented CVs, not necessarily the best qualifications, will be the ones who receive interviews.
