Differed to a large extent between East and West Germany. The East always maintained (not totally inaccurately) that ex Nazis were on the whole given a pretty easy ride in post war West Germany. The process of de-Nazification in West Germany could be (I think) regarded as a something of a joke, the Western allies were never very enthusiastic in pursuing it after a few years other than for symbolic causes, and there was an underlying view that the past was the past and most people just wanted to get on with their lives and forget about the Nazi past. Many average Nazi party members never really had their past held against them and there were not efforts to make it particularly hard at all for them to get jobs in almost any sector and it was mostly brushed under the carpet.

In the East much more was made of ridding public life of ex Nazis, mostly for ideological reasons, this is not to say of course that many ex Nazis did not rise to reasonably prominent positions or that there were no ostracising, but it de Nazification was considered a far more important issue in the East than in the West, that much I would content is irrefutable. A senior East German politician (Albert Norden) authored a famous book in the 60s I think called the Braunbuch where he listed huge amounts of ex Nazis in prominent positions in West Germany, although I believe that the reliability of this book is pretty questionable and not all of them could be proved. (I think West Germany produced a similar book in response covering ex Nazis in the East but its name escapes me.)

There is a really interesting film called Labyrinth of Lies that came out a few years ago all about trying to bring ex Nazis to justice in West Germany, great film and really worth a watch if you've got any interest in the subject.
