My Qualification BE mechanical engineer, I'm not relevant in IT field, Currently Working in oil & gas field
Your chances of finding work are much higher in oil producing countries than in Poland. Try the US, Canada, the UK, Norway, Indonesia, and the Gulf States.
All of the best jobs are advertised solely by word of mouth, human to human. Recruiters and internet sites get only the table scraps. Ask the people in your professional network, especially people who have worked in the oil and gas industry, and, if they don't know, then ask them if they know of anyone else who can help.
You're basically wasting your time with recruiters. They rarely get the best, most interesting jobs in the best places for the best money. Like I said, those jobs are advertised face to face between people who know each other. If you need to build up your professional network, then do so. Especially go to conferences and conventions with foreign guests, and be active in meeting people and talking to them. Don't be shy.
