Very fun. Amazing interviewers. Chill talk, organic topics. Not the tipical nerd engineers. After the first screening you are given a task, also very fun, like the hunt of a treasure to test your basic understanding of concepts and you ability to solve problems, real world problems. Then you are invited to a causal lunch with your potential colleagues. A classical Finnish lounas, you get to know the office. If all goes well, you are given and offer.
