Developers salary

As a developer I'm always searching for jobs offers on the Internet. I'm always wondering how much they can pay me for this position? Here, in Poland talking about salary in job is taboo. There are only few offers in IT which we can see salary before we go to the conversation.

It is rather strange and many of Polish companies are abusing this fact - I've been on countless interviews, wasted huge amount of time to get there, to obtain some information about company, etc. only to hear that they can give me only about half of my financial expectations.

I must say that I'm disappointed about that. Many of my friends from University or from my few past jobs are working for very small salaries according to what they can.

I think that in Poland we must wait couple of years to catch up to other bigger coutries in this topic. In my opinion on every job offer should be information about salary (it could be with some margins). It would spare everybody some time.

According to that I've googled some about developers salaries and I've found interesting article - "How much should you pay developers?".

Author of it says about few principles about financing development team.

Firstly algorithm is giving points in few categories. Each point is worth some money - there are no margins - it must be clear and fair for everybody.

Secondly another principle (my favourite) is transparency. Everybody knows how much others are earning and knows why - it can clarify what we need to do to earn more - and there is no situation that I'm not satisfied because of my colleague who is earning more than I but he has less experience. It is clear for everybody and team can even talk about their salaries in public.

Another principle is competetive - if we'll know that in company X we can acquire twice more for doing the same it's obvious that we'll quit our current job to take another. But if we don't know we can stay there for life. Companies should use this information.

In Poland many companies are very greedy. I've met and I'm still meeting managers who are searching for IT specialist with minimum 3 years of experience and offering them salary of a shop assistant. It's sad even more if we realize there are some people who will agree working for them.

So to sum up my point is that there should be information about salary on every job offer and we should always check if this salary is fair for this position.
