Thanks guys. should i tell them, that i am open for any position and they will determine what job will be correct for me or how does it work?
All of the advice other people are giving is good advice, however it does not answer your question.
if you specifically want to work for Bartlett, they will probably only be able to get you an entry level position, such as Decontamination technician. One of the other Bartlett companies called "Sun" hires engineers. I don't know their number, but you can call the 800-225-0385, and tell them you are desperate for a job, and would be interested in both a decon job (if you are really desperate for work) or fro the number to sun, and see if they can get you engineer work.
Again, the other suggestions are good ones, they will get you work, and at much better pay, just not 'today'. do all of the above, some will take longer than others and some will be faster, then you have a backup plan, and a long term plan.
The more info you give us, the better we can help you.
