Google is definitely a great place to start, as usual. Depending on where you live you may wanna look for game dev meetups/groups, I always think connections made in person are stronger and more likely to pay off, but that may just be my preference.
There’s a ton of communities online that can help you find people to collaborate with to get some experience and exposure. The obvious places to begin are the forums for the individual engines - Unity in particular has a phenomenal community. Aside from those, there’s certain subreddits that are pretty great; r/gamedev and r/gamedevclassifieds in particular. The latter has postings for jobs and projects that need filling, as well as people marketing themselves for jobs and projects. Another two that I can think of (off the top of my head) are IndieDB and TIGSource. Both of them are communities with helpful people and job postings.
If you have any other questions, feel free to ask at anytime! Like I mentioned on my prior post, the most important thing is that you find projects to work on and expand your skill set. Look for things outside your comfort zone and continuously build the skill. Extra Credits, one of my favorite game design theory resources, has an awesome video on it:
