The best place to start is talking to people you know and checking if they have the in with any good jobs. Then if that doesn’t work, apply directly for jobs you find by checking with individual companies, ideally speaking with the hiring manager first. Jobs listed on job boards are really difficult to get. You’re up against everyone, and they have filters that accidentally discard a lot of qualified candidates.
It’s about as dangerous as using IE in the old days, or Edge in administrator mode.
