Dude, not everyone here understands your abbreviations. If you sincerely seek any sort of help, please provide more details and explanation so that the forumers here can help you make a decision.

I think as a product test engineer in Infineon, you will most probably be controlling the QA folks especially the QA operators. I see the promotion as a good way to retain your services and it may take you a while before you get promoted in Infineon unless the job scope means that you are already at a high position (Senior Engineer or manager).

You can hear a lot of good things in Infineon because its a MNC compared to your local company. Don't get me wrong but what do you see yourself doing in the future? If you believe that Infineon can offer you something more, then go ahead. Else, if you do stay, you can gain a lot of experience and valuable project management skills which in the future can be very useful for your own resume.
