Hello there.

The honest bit first: I am not the right person for a deep Java/Spring/Kafka/AWS briefing. That is not my daily stack, so I will not pretend I can coach you through it. Nokia is a big place and the interview will follow the job you applied for, not a universal “learn these five tools” list.

If the posting is Java/backend, you are already in the right neighbourhood. I would not go hunting extra frameworks for just the sake of it. Know your own work well enough to talk about it simply: what you built, what broke, what you would do differently. Confidence shows and that usually travels better than keyword bingo.

On my side of the product we live more in C++, Linux and large existing codebases. It's less shiny new stack, more “please don’t break the prod(uction)”. For me personally the cloud alphabet soup is a nice backpack, not the cheat code. In my interviews it was example problems and questions: think through a messy one, explain yourself clearly, show you can learn fast.

Whatever the profile is, remember to think out loud — they cannot give points for a brilliant silence.

On AI: skip the benchmark Olympics. More and more teams are using it, some interviews will never mention it and I can only speak for people like me. If the posting asks for it, talk about how it helps you day to day - real talk, a bit of prompt hygiene and the habit of checking what it actually gave you. If it doesn’t, don’t build a shrine to it.

Good luck!
