Average Negative Helsinki, Southern Finland

After an initial recruiter touchpoint, I later got pulled into a task-based stage. The assignment involved navigation route calculation, and I completed it and submitted it over email. The task was reviewed and approved, and after a few weeks I was invited to another interview on Teams.

That Teams meeting came after the project work step, so it felt like they had already aligned on what I could produce from the task. The overall pace stretched out a bit, mostly because of the time between task submission and the next scheduling.

My first steps were pretty structured. I was introduced to a project manager and developers who worked on the same project, and the PM showed me what they were building. Early on, they asked me to introduce myself, which set the tone for how they wanted to think about my background.

Then the interview shifted into the technical part. Most of the questions were C++ related, and they kept coming one after another for about the first thirty minutes. After that, they gave me three separate coding questions to work through.
