How do you know if engineering would be a good career for you

I would say, if you had an interest in science, mathematics and the research and application of such topics, then engineering would suit you.

But, the U of Illinois thinks it is more than just a love of math and science. Here's what they say:
Engineers like identifying problems and figuring out solutions. An interesting problem becomes a fun puzzle for an engineer – with problem, goals and limitations in mind, engineers enjoy coming up with various solutions, seeing what works, and tweaking what doesn’t. Engineers notice what people struggle with their everyday lives and like to think about how to make life better and easier for people. Yes, engineers are good at applying math and science, but they’re also good at listening, defining problems, speaking and writing to convey ideas, and thinking creatively. If that sounds like fun, engineering might be for you.

**But remember if you pursue engineering for awhile and decide it isn't for you, you can always find something else you like better!

you need to spend alot of time in school, doing alot of work by yourself.

in the real world engineers are expected to know everything in and beyond their respective field. and as an engineer you should be ok with trying to learn everything in your field.

You work well with a team
You are good at technical fields
You are good at analyzing results and understanding implications
You like working in interdisciplinary settings

There are tests to determine your appitude and interests. Maybe you should consider taking a few.

If you can picture yourself doing it
