Work / Questions regarding Job Opportunity in Warsaw as an IT Business Analyst [3]

Greetings for the day!

Currently i am exploring job opportunity with a Dutch based tech MNC ( I hope you will understand which company :-) i dont want to reveal the name out here).

So this would be an internal job transfer as a IT Business Analyst.

Currently i have total experience of 4 Year and 3 months with close to 3 years as a Business Analyst

1) What could be the possible Salary which would be provided according to this experience? Just wanted to get an estimate so that i can put forth my thoughts while carrying negotiations with them so that i know is it below/above average.

2) I have seen, enormous number of posts which discusses about cost of living. Does it differ from city to city? Cost of living in warsaw is different from some other city ? How much does the cost vary?

3) For a decent living i assume, cost of 4500 PLN is a minimum?(Rent, Utlities, Internet, Food items etc, transportation) Yes/ No or even more? - if i set up 5000PLN is it a good life?

4) How is the transport infrastructure(Roads, Railways) ? Law and Order ? Pollution(i assume when compared to india it would be very less)- essentially translates to quality of life

5) Would language be a big issue in interaction in day to day life?

I have got few queries more which is dependent on the above answers. Will put in those later.

Thanks in advance for your answers. and i must say this has been a wonderful community for those wide range of help you guys provide to ppl in need

Cheers!!!
