I left my job and I wanted to rewrite my CV  some months ago for sending it to many companies but none call me back. I didn't understand why? but one friend told me that my CV is very simple and bad. I began to search for information on how to write it in the best way and I came across Web Developer Resume Sample template. I wrote after it and after sending it, I was called in some days.
