Between midnight and 3am, when everybody was asleep. They knew exactly where I lived, first of all: a few days before I was captured, a fellow came. They had a key – they had everything to the apartment, to the door. There was one interpreter who told me [in German]: "Get up! You are being mobilized to work in Russia", and there were about half a dozen soldiers with machine guns, who surrounded me. When I wanted to get to the toilet, they checked it out first to make sure there was no escape hatch. It was a very tight operation. They did that with every family. Many families came, while I was alone. -Fritz Karl Preikschat

The Soviets were only interested in skimming off the specialist knowledge of the technicians and engineers in order to be able to develop their own missile program on this basis. At the end of 1947, the German scientists had done their duty when these replica German V2 rockets were repeatedly successfully launched, and then the Soviets took matters into their own hands and a year later, in November 1948, they had the first launch of the Soviet ones, which were developed by Korolev who completed the R1 rocket based on the German V2. -Daniel Bohse

I'd say they handled it semi well, atleast they didn't immediately put nazis in positions of power like the US and Britain. Unfortunately a few did attain powerful positions after returning to germany. They were also paid well for their work which unfortunately is a human right even for nazis.
