Git Gud.
Ok, that's not terribly helpful, so here's a more nuanced version:
1) Have an online portfolio and make it as AMAZING as possible! Don't put up everything you've done, only the BEST of what you've done. Good isn't good enough, great isn't good enough - only AMAZING gets to stay. People will remember you by the WORST thing you presented.
2) Have a LinkedIn profile and keep it updated. Recruiters are increasingly relying solely on this to find prospective employees. (Not entry levels yet, but that could change in the future.)
3) About 85% of all game dev jobs are staffed by internal references. So join professional networking events. Look for meetings with your local IGDA (International Game Developers Association). Many of these meetings are online during the pandemic, so you have a chance to start networking from home! Also, join game dev forums, chat groups, Discords, etc. Remember that networking isn't about begging people to give you a job. Rule of Thumb: You aren't networking today for a job tomorrow, you are networking today for a job 3 years from now.
4) Also, "git gud" - continue to improve your skills in whatever area of game dev you want to work in. If you have no portfolio, work with other indies on side projects. If you are a coder, contribute to open source projects. If you are an artist, volunteer to make art for local non-profits, community groups, or school/community/religious events (you can also do icons for open source projects). If you are a producer type, volunteer to do the grunt work for an open source project or volunteer to run something for a local/community/non-profit group. If you are a sound/music person, contribute to OpenGameArt or work with a voice actor to take a public domain book and make an AMAZING audio recording of it with sound effects and music then put it up on LibriVox. THESE ARE RESUME AND PORTFOLIO PIECES!
