I have never worked in the large IT-corporations, and it is very interesting for me of how much work advanced level developer has to perform during the period of, for example, a week or month.
So what is the average performance and intensity of work of such a high class professionals expected by employers?
I understand that the question is a bit abstract and the result depends on the set of different factors in every particular case, but I think that it is possibly to do the average and rough estimation or to give an example.
