How to apply for a Schengen business visa without being asked for a work permit?

I am a Sri Lankan. I was offered a job as an Software Engineer, from a Swedish company who are expanding to Sri Lanka. After a series of interviews they have invited me to visit their offices in Sweden. I am still not employed by them. If employed I will be working in Sri Lanka, not Sweden.

I applied for a Business Visit class Schengen visa through the Norwegian Embassy (Sweden consulate in Sri Lanka only handle work permits) as advised from my potential employer.

Today I got an email from the Embassy that they feel what I plan to do in Sweden requires a work permit rather than a business visit visa, and that I should explain to them why I think a business visa is sufficient for me.

Purpose of my visit, as stated in the invitation letter submitted with visa application is,

Introduction of their Software functionality.
Study and analyze the source code.
Create and present future architecture in concept form.
Propose future business case.

I would like know what parts of this schedule may be considered 'work' that cannot be carried out on a business visit. And how should I make my case, if possible, that I am qualified to visit Sweden to do above on a business visit visa?
