The first and most crucial step that you have made for which you deserve a pat on your back is that of identifying the opportunities that the Fmcg jobs present. But, you need to keep in mind that you have to follow a certain procedure for you to apply for a job. The very first procedure is for you to identify the site from which you would make the application from. 
You would need to register at the site and get a user name and a password that would help you apply for a job. You have to be honest during this process. You would regret if you falsify the information you give because this is what the employer would use to refer to and identify you.
From the very beginning you have to be honest with your employer. You would need also to be sincere about the expectations you have from the job. The salary expected has to be within reasonable margins. You may be required to state what you earn at present and you also need to be sincere here as well.
At the end of it, you would need to give some two or three names as references and contacts as you apply for the food production jobs. These names have to be good in that they should be real people with real information about you.
