I wouldn't know, since we're not doing the same job.
I'm a mechanic engineer, modeling stuff on computer, and running programs to make sure it's "stable" and can hold the loads, and if not, improving the structure.
Personnaly, the start was a bit boring. Not even tough, just boring. I actually managed to do what was asked of me in way fewer time than what they expected. Probably because all the previous people were lazy. And future people will do the same thing, since i continued in that trend. I was then asked to work for a way bigger company, because they needed manpower for a huge project, and don't hire people since it would be a pain to fire them afterwards. I've been there for 6 months already, and the work is way more interesting and challenging. Even if i also stay on my computer most of the day, i know why my work is important, and i basically just like it. Working 37,5 hours officially, probably around 40h actually, but time flies by so quickly.
There's always temporary boring jobs, needed before doing the interesting ones, so it's not 100% fun. But still worth it.
