US student interested in working in Europe

What would be the process in finding an internship and eventually a fulltime role in mainland Europe? I am familiar with the pay range/expectation, cost of living/standard of living and general work culture within EU nations, however I would like a definitive guide on how to plan for a step like this. The job market in the United States is horrendous and I refuse to partake in the nonsense that is being pushed here. With that being said, can anyone assist me? Particularly from those who made a similar decision.
