BlackBuck (Zinka Logistics) runs one of India's largest trucking and freight platforms, so its engineering interviews lean hard into system design for high-throughput logistics, real-time truck tracking, and payments across a fragmented fleet-operator base.
In 2026 you should expect a coding screen followed by design rounds that probe how you would model load matching, GPS ingestion, and settlement at scale. The bar rewards candidates who reason about trade-offs under Indian tier-2 and tier-3 network and data-quality constraints.
