While pushing for a result from an interview is more of an advanced move and I do not recommend for you to do it, there is one thing you absolutely can and should do - send a followup email thanking them for the interview!
It need not to be long, something akin to the following template:
"[Whatever is correct greeting in your culture],
I wanted to thank you for the opportunity to interview with you
yesterday, it was truly an eye-opener to learn about XYZ you've
mentioned, and to learn so much about your business, I had no idea
that CVM was so popular before! It was very educational indeed, and I
cannot wait to hope that we will have the opportunity to work together
Fill in the blanks and adjust the tone to match the one you had during the interview and off it goes. This will remind them that you exist, show that you were paying attention and is also a great time to address some gaps that may have come up during the interview,(like that mentioned XYZ which you absolutely didn't know about before, but have now educated yourself bout).
