Nokia interview questions

I applied for a job in Wrocław, Poland. The company responded very quickly (first call from HR the next day, interview one week after). Between first phone call and interview, I received a Codility test to check my skills. Now, that I look at the interview, it wasn't difficult - the problem was, I never actually worked as C++ dev (worked in other programming languages) and didn't turn out to be as "fluent" as they expected. No hard feelings though, I think, I will give it a try again after some time.
