I think the year in Europe backpacking is fine … New hires are not like 50 year old laid off people, it is not shameful to have a gap year, just have some good stories to tell. And with the internet, you can still pound off resumes to promising ads and you can fly home from Europe in a few days, if something really seems promising.
I did not say to take a job for 12 weeks by lying about your intentions, since I don’t really understand why you would quit … unless it is something you just don’t like (and 3 months probation is pretty standard, so your company can also just tell you to pack your bags and go with no unemployment). If the plan is to quit after 12 weeks … not sure why … then no. That is dishonest.
But … there is also no really truly bad new hire job, especially if your search has gone on for long, or you have financial pressures that mean you need to work now, not later. I would say stick it out a year to get full value …
If you can get a job that seems remotely interested at a large company that does have work that interests you, I don’t think it is disingenuous or even in any way bad to take that job and apply for internal transfer after a reasonable time, unless that department is spending a lot of time and money training you.
If you have computer science or CAD skills, then I would personally chose them over an internship that clearly states they don’t want graduates.
Sorry to tell you, but engineering degrees are primarily basic science and math and some made up projects to teach students how to solve problems. So any real job will take training or mentoring or something. Summer programs include some company sponsored activities so the department doesn’t have to spend 40 hours a week entertaining your student … and yes, these are recruitment programs for high achievers.
And new hire jobs … .well, they vary tremendously, like engineering itself, so there is a bit of luck involved in finding the right niche. Really, the goal is to find a company that will help you grow into a professional by training you and allowing you to find your niche … which could easily be project management or factory floor work or high tech design (believe me, most people do not want to do this, since it is hard).
