Will my age affect my chances of finding a funded PhD position? I just finished my masters studies. My question is, will my age (29) affect my chances of getting a funded PhD position? I finished Bachelor of Engineering when I was 24 (took 6 years to graduate, normally my program was 5 years). I worked as a Lab course assistant (teaching the practical part of the course at a local university) for 2 years before I started my MSc a bit late due to financial reasons. I started working in industry a year ago (for same financial reasons) in a computer science field but irrelevant to the research area. I know that most of PhD scholarship positions officially require the applicant's age to be under 35, but do not they prefer someone who is 25 rather than 34? 

I have two conference publications, one in IEEE, and about to send the third for journal publication. My field is computer engineering with a focus on the software side and I am trying to apply in Europe mainly.
The short answer is: no. Quite the contrary, many universities value the experience (preferably from industry) so it is beneficial. Also, your conference papers will be the most important factors in getting the PhD position and/or funding. I'd also emphasize that you should highlight the fact that you have a journal article (preferably A or A*) in progress.

I have not seen any such requirement which is restricting PhD or any academic degree to a specific age. In fact, doing so is illegal in most (read: all) European countries as it comes under age discrimination. 

To narrow it down further, different funding bodies could impose their own restrictions per project, for instance DAAD's grant that you mentioned is "to promote and fund young artists" according to them, that is why it is restricted to a certain age group. A similar example could be feminist studies where it could be restricted to a single gender. Again, this has nothing to do with general conditions of admission.
