Interviewed for a senior software developer position through an invitation sent via Telegram. The first round unexpectedly included a live coding exercise, with minimal feedback afterward. The second round focused on a data-related project involving user click patterns and recommendations, which was interesting but felt outside of a standard backend scope. The final round included a maze pathfinding puzzle, followed by a large-scale messaging system design task—both squeezed into roughly 20 minutes, which was insufficient. No feedback was provided in the end. Overall, the process felt disorganized and lacked transparency.
