Moving from Scotland to NRW, Germany

I'm 22, currently single, living in Scotland and do not speak a word of German. I've been offered a job in Euskirchen and I believe the job pays around 38,000 Euro a year. Obviously I will have to relocate to Germany for the job, which is what I'm wanting some help and advice on. I really have no idea what to expect.

My interviewer said it would be best for me to look for a flat in Koln or Bonn as Euskirchen is a small village, not really suited for a young lifestyle. Since I've never actually been to either city, where would be better?

If I accept this job, I do intent to learn German, but for sake of initial ease, is an English speaking population common in either city? Also, another this is that I don't know anyone in Germany, so are there any sort of English speaking clubs and stuff?

It's a great job opportunity I've been offered but moving to Germany myself is making it a little bit scary and so much harder to decide what I should do. Any other advice on points I may not have thought about would be greatly appreciated.

Bonn is pretty sedate, so you'll probably want to move to Köln. See the relevant thread for more info. There's more of an expat scene in Cologne, not least through Toytown. Type "Cologne" or "Köln" into the search box to have all your questions and then some answered.

With a population of 55,500 I´d call Euskirchen a typical Rhenish town ... with all the facilities one would expect of a district "capital"

I didn't realise Euskirchen was that big. I was only saying what my interviewer told me, I guess he meant in comparison to Koln or Bonn.

Having a good read through the forums just now, but I'm wondering, since I don't speak a word of German at the moment, what's the English speaking scene like in Koln?
