With that kind of experience, you should command a much higher grade code and salary. Don't take the 1st offer these companies give, it is always way too low. Ask for grade code 15 and at least 20,000 per month. You worked as a manager for god's sake, you are not some young high school computer nerd. Also, your age is 50+ and you need to maximize your earnings before they force you to retire at 60. These companies rely on your ignorance about the country and salary options.
