Actually, this is being discussed on another thread at the moment. Read all about it here: https://polishforums.com/study/quality-issues-politechnika-wroclawska-74688/
Short answer: There is little reason for an Indian student to study in Poland. Although the cost of tuition may seem low, the quality of education is also low, especially in programs taught in English. Also, there is very little chance that you will be able to find part-time work to finance your studies.
Job opportunities for recent grads are few and far between, and it is highly unlikely that you will find work in Poland after you graduate, or would want to stay. As far as finding work in richer countries is concerned, you would be no better off than if you graduated from a good engineering school in India. Also, if you want to study engineering, study highly paid fields like petroleum, geological or biomedical engineering rather than mechatronics. There is a lot of money spent on prospecting, and when the economy goes bad, this is one of the very few fields where spending goes up, so it is recession-proof. You could do a sub-specialty in automation if you want as part of your studies. Your lifetime savings potential would be significantly higher if you studied one of the fields I mentioned.
Either stay in India and study a highly paid specialty of engineering at a good engineering school there on the hopes of getting into a good graduate program in a richer country, or take a year off and study math, physics, chemistry and English very hard to get admitted with a scholarship to an excellent engineering school in the US, another English-speaking country, or a rich Western European country like Germany, Switzerland or Sweden. Or South Korea or Japan.
Go where the R&D dollars are. There is very little R&D done in Poland. R&D spending per capita in Poland is only 14% of that in the US or South Korea.
