Writing a resume is difficult, but more difficult is what to write in the resume. Everyone has a different idea about how to make these things win. However, there are some dos and dont’s about resumes that one should definitely understand.
Never list all your jobs on the resume. If you write down every job you have had, the future employer well think you are unstable and perhaps will also leave his company soon. The resume is not a legal document, but is an advertisement about you. You highlight what you want and then can talk about any missing gaps when asked. And always be honest about it.
When you send in your resume, avoid folding it to fill the envelope. Better buy a larger envelope. In addition, do not staple or clip the resume. Keep the resume simple and easy to access.
Some people add a very large photo to their resume. Unless asked to submit a photo, one should avoid this practice. You never know what the employer(s) may be biased against: may be they do not like certain features of your body, your hair, your sex, your weight, your ethnic make up, etc.
When asked to send a photo, do not send one which is almost half a page. Send a small decent size good quality picture which reflects you. Dress well for the photo-do not send a tacky picture of you playing tennis. A 2 x 2 should suffice.
