Applied through the company's career website. After several weeks, got a request to do a coding assignment without any prior call (e.g., CV screening). Took 4-5 and made a big effort to do the assignment in the best possible way. I was very confident of the positive outcome (next interview round) as vehicle routing optimisation is something that I have been successfully doing for many years and different clients (companies). Without wanting to sound arrogant, I believe to be an expert in this problem domain. After one week, got a generic rejection email that they decided not to move forward with the candidacy. It was such a waist of my time.
