You have one year of experience. That experience isn't worthless, but it's specific value depends completely on the context of the potential new position.
Someone who graduates from college and works one year as a shoe salesman has one year of experience. That may have a lot of value when applying for a position as a clothing salesman, and may have less value when applying for a position as a chemist. Still, it is one year of work experience more than another candidate might bring.
Whether your one year of experience translates into an entry-level salary or more than an entry-level salary for your next job depends on
- Your abilities in the new role
- The new company's requirements and budget
- Your ability to convince a potential new employer that you fit in their more-than-entry-level position
Essentially, the specifics of the situation will determine what you are worth. Nobody here can predict that.
If I change to a different technology would I be considered an
entry-level worker, and thus given an entry-level salary, or would
they count it as one year of experience?
Maybe. It's not automatic, but the new technology may be different enough from your current (1 year) experience, that you would be considered entry-level and only offered entry-level salary
What if the new technology has no relation to my current technology
like working in java or embedded systems?
Maybe. Probably more of a chance that your prior experience isn't relevant enough to elevate you beyond entry-level status.
What if the new technology is slightly related to my current
technology? (For example, as objective-C is a super set of C)
Maybe. All experience has some value. Perhaps the value will translate into more-than-entry-level pay.
Realistically, one year of experience isn't very much. And (assuming you started at an entry-level salary 1 year ago), you probably haven't progressed much salary-wise anyway in just one short year.
If you are really interested in a different technology or career path, you should feel overly burdened by the difference between entry-level salary and entry-level-plus-one-year salary. Consider the long-term instead.
