How would I know about your engineering project. However look at the following:
If I see from the prospective of knowledge, challenge, I would recon my final year project of undergraduate. I worked on (project name). It was quite intensive due to the fact that I was doing research and knew that this could be unachievable. However, due to my intense literature review and guidance from my supervisor, I was able to finish it in best possible manner.
You can add little bit detail of your project as well.
I haven't done a engineering project but I have done my little own project within IT. I had to create a website based on a business. =) I based mines on something I am anyway interested in - Henna mehndi. =p
Made Websites and records for customers IT
i havent really done any :/
havent done any
i've never done engineering
dunno
Well being a software engineer myself - i experience tough challenged every day - fixing bugs and issues with different systems.
I think the most challenging project i have done would be any and all my assignments, they were hard for a reason and once it was accomplished i felt relief. Take all challenges as they come, nothing is ever easy.
i hope i have helped and be sure to keep yabbing =)
