Interview process was very reasonable. Initial interview before task, and technical interview after the task. Both online. Good setup, good pace. What I like about the company: they have modern stack, quite unfamiliar to me, but I am willing to learn it. They have a nice problem to solve: estimate arrival time. They have a nice homepage, and blog. So overall impression is very good. I feel like we could have a good fit: I have some useful skills for them, and I have something to learn. The test task was a shortest path problem. I tried to solve using a generic Dijkstra algorithm. The generic part means that the algorithm should be reusable in other problems which have similar type. Since Node.js was preferred language I decided to use it, even though this was new to me. Eventually I am not 100% satisfied with my solution, but it's decent. "It is difficult to write poems in foreign language", but I am learning it. After submitting I asked for a code review to get feedback where I messed up. Unfortunately there was only 1 reviewer. And he did not understand the code... He tried to eliminate the generics part. The initial response to my solution was "nice job", but eventually they rated it as 4/5 and 2/5, meaning it was mediocre by their standards.
