9. Poorly organized While writing your resume, you should maintain a proper order of importance. Don't mention about your hobbies at the starting. Moreover, job titles are more important than dates of employment. It's better to put the educational details at the end. If you are a fresh graduate, then only you should highlight it. More significance should be given to those information that meet the need of the employers. 10. Typos and Grammatical Errors It may sound insignificant, but a small spelling mistake or grammatical error can cost you the job you are applying for. Your resume needs to be grammatically perfect otherwise it will create an impression of a careless person in the minds of the employers.
