Just a reminder, that "an interesting work" wouldn't work here.
When work has the meaning of profession, it's uncountable. So, using the indefinite article sounds kind of awkward.
When work has the meaning of construction or engineering project (έργο in Greek), it's countable.
That's why there are phrases like "a work of art", "road works" but also "a lot of work" and "I've got work to do".
