On the entry for your job you are no longer working at, add the final date you worked there. Take a close look at the content you have included in this section. Update the info as to your duties and the skills you developed while working there.
Depending on the circumstances of why you are no longer working at that job, you may want to consider making a list of who you can approach for work – related references from your former coworkers that you can use in your upcoming job search.
If the circumstances leading up to your dismissal are still emotional and you are sensitive to it, you may want to spend some time practicing telling an interviewer why you lost your job.
The interviewer will likely notice the break in your work history and they are going to want to know the why behind your job loss. If you plan for it in advance you can create an answer that doesn’t shake you up and provides info on how you learned from that job and can take what you learned to your next position.
