Currently looking for a job in around the same field, and I think LinkedIn is not as mandatory as people can make it sound like.

Most often offers are listed on different other platforms or directly on the company’s website. You’ll definitely miss on some offers but not all. It also depends on what type of company you are looking for, as I find that most big companies are LinkedIn only.

Overall, imo it may be more difficult depending on what you are looking for, but definitely doable

I have been using Bruno and I am quite happy with it (+ you can version and share your projects) https://www.usebruno.com/

Game soundtracks, mainly World of Warcraft because of the sheer amount of different music ambience and also because of the nostalgia hit.

I recommend https://youtube.com/@meisio for very very well crafted videos of pretty much every zone the game has or is offering.
