Fumble my way through …

Could you give me the exact definition of the phrase? Does it mean to do smth awkwardly trying to deal with smth? Does it always mean that I managed to deal with the situation? For example:

I fumbled my way through the interview telling some jokes.
I tried to fumble my way through an exam but I failed it anyway.

Or it also can mean some failure (cause you do it awkwardly, not smoothly)?

Thank you!

You basically have it! The only thing I think I need to say is that fumbling through usually means that the task was completed, even though it was not done well. In the second example, you would say: "I fumbled my way through an exam, but I failed it." Trying to fumble through something would usually mean that you didn't complete it, like: "I tried to fumble through the race, but I collapsed midway through and woke up in the hospital hours later."
