Hi Johanna! That’s a great question. Unfortunately, the short answer is that it’s different for every company. Some recruiters love to read cover letters, others never read them. I would say that if you’re trying to make your resume fit on one page and have to make a choice between including really great work experience and including an objective/summary, go with the experience. It will show why you’re right for the job better than a brief summary. Again, that’s a personal opinion and everyone will have a different view on the matter. But go with your gut and include what you think shows that you’re the best candidate!
If you are looking for a job, then it is very important that you understand how to offer yourself in the best way to an employer. This is done by writing a 'CV' (curriculum vitae - Latin for 'life story'), Called in some countries a 'resume '. Different countries may have different requirements and styles for CV resumes. So you must follow the correct practice for your culture and country. However, we will try to give you important principles and advice. A CV resume is quite simply an 'advert' to sell your self to an employer. You should send a CV to an employer when they ask for one in a job advert, or when you are enquiring if any jobs are available. So the purpose of your CV is to make you attractive, interesting, worth considering to the company and so receive a job interview. An employer may have several hundred enquiries about a single job; he or she will only choose a few people who appear suitable for interview.
