I am a physics PhD student in Germany. During my PhD I got two children, and as a mother, I had to give major part of my time to my children. I started in April 2012, and I will finish in spring 2018. Is this too long time to get a postdoc position afterwards?
The typical times for a PhD in Germany vary mostly between three and six years, depending on the specific field you're in.
Legally, the university is allowed to give you fixed-term contracts for a total maximum of six years while you're working towards your PhD. However, there are extensions of this limit for childcare, so you would be well below this limit.
For a postdoc position, I don't think the time taken for your PhD would be a major factor in evaluating your application.
I was a resarcher fellow in Fraunhofer institute in Erlangen for a few years (7). I was surprised by the time take by PhD Candidate to defend a thesis.
I think that the average is 6-7 years. In comparison to French system it's really long, 3-3.5 years here.
To get a post-doc position, I think age of candidate is not a problem. For me only the quality of the guy (or girl) is important!
