I applied online. The process took 2 weeks. I interviewed at Grid Dynamics (Belgrade, Central Serbia) in Feb 2025
Interview
Going through the CV, and discussing past projects. Then I was asked about kNN, additionally, if we have k known, how do we optimize it? Then we proceeded to the technical coding challenge. After that Q&A discussion. The whole process took almost 2h.
