Nokia Software Engineer interview questions

The recruitment process consisted in a preliminary stage and 2 interviews, first one technical, about 60 min, and one with an HR, also 60 minutes. Preliminary stage: I got a 2 hour online test with 7 sections, 5 of them got several OOP and DSA questions (basically a Google rush) and 2 sections each containing a coding problem. Technical Interview (C++): After 2 weeks I'm invited to an online interview with 3 senior engineers. The questions asked were much harder than normal because I had a certification in C++. I answered correctly half the questions and managed to get to the final stage. HR Interview: Normal questions about how I manage stress, how to I work with a team etc... Offer: After the HR Interview they called a day later to propose a date to make an offer
