Congratulations on your graduation! I think you will be able to make a good decision on what path best works for you only after you have been working in the industry for a little while (~1 year) – whether as a manufacturing engineer, production, reliability engineer – really anything related to mechanical engineering. You may actually discover that you like doing something you initially thought you would never enjoy doing. As a young professional, that just started her career, there is plenty of time for you to grow and learn and change career paths down the road. For example, I started as a medical device engineer. I changed my job 1 year later because I wanted to do something more technical. Currently, I work as a design engineer; I also get to work with manufacturing plants, sales engineers, applications engineers and test engineers. So my current job offers insight on what other engineering jobs are available in my company, and at the same time gave me a pretty good idea of whether I want to switch to any of them down the road. For example I know that I do not want to be an industrial engineer or a test engineer but I may be interested in switching to a sales engineer position because I like interacting with people.
You said that you want to work abroad, but you do not mention where you currently live and where you would like to work abroad – would you like to work in Europe, or US? The answer to the previous question may or may not pose further limitations on the specialty you want to pursue.
No matter what path you choose you have some very exciting choices in front of you as a mechanical engineer professional. I wish you well and good luck!
