All project participants, responding to vacancies, accept the conditions that for the period of participation in the selected project the work is not paid until funding is received or unless other conditions are specified in the vacancies. The time you spent is investment in the project that you choose. How each team member and the team as a whole works on the project determines whether this investment can be converted into money or not. In any case, your resume will become more significant if it contains information about participation in real projects.
