What Adobe tool should I use for it?

[Cherich_Dorattioti]

I'd like to have an interactive Resume in PDF. 
I made a minimalistic resume using MS Word, which gives me the possibility to expand/collapse titles and paragraphs. 

this result is good enough for me, but it's quite unprofessional send it as a Word file, I need ot converted to PDF. But PDF doesn't keep the function at all. 
i've tried animate, Indesign... Please someone help me as i need to apply for a new job!! 

Thank you in Advance!

i made a 10 sec video showing...

If you make it as an interactive PDF, there's no guarantee that your interactive features will work in all of the myriad available PDF viewers (except for Acrobat). And you definitely can't control what PDF viewers will be used to open your resume.

I wonder if you considered just making your resume as a web page? It will look the same in any browser, and accordion with expandable titles is relatively easy to implement. 

(I don't know though if it's acceptable to send your resume as a link to a web page as I didn't send out resumes for quite some time.)

It has been a long time since a clever résumé could catch the eye of a hiring human, so from the days of using outstanding paper or a slightly odd size or nice layout and graphics and the like, to anything animated, interactive or otherwise "sparkly," all of those time-worn tricks are pretty much obsolete.

Text in a clean, ATS-compliant format is all that matters any more, since no human will see it unless it can be wholly parsed, categorized, keyword-counted and template-matched.

A nicely-formatted version on "résumé paper" is still a nice gloss at a first interview... assuming you actually get an in-person interview.

As Leo already pointed out, this is not a good idea since you can't control how the file will be handled and interactivity in PDF is wonky to begin with.

Machines read resumes before a human even gets to look at it. Make a nicely styled resume and be done with it. Most employers want a Word file.

Along with the fact that interactive elements do not work on all readers/devices (as mentioned), the expandible/collapsible menu is basically impossible to achieve in Acrobat.

Make it simple, no animations. Anything like this would exclude recipients. Use InDesigg, no background colors as they would cause a waste of ink when it is printed.  
InDesign has an awsome typography.
