Blinkit’s hiring process for engineering roles is highly structured, consisting of three core rounds: Technical (DSA + System Design), Managerial/HR, and Cultural Fit. For entry-level roles (SDE-1/New Grad), the focus is heavily on medium-level DSA problems and resume-driven technical discussions, while SDE-2 roles emphasize low-level design, scalability, and leadership principles. System design rounds are consistent across roles but vary in complexity, often requiring high-level architectural diagrams and trade-off discussions. Cultural fit rounds are universal but less technical, focusing on startup adaptability and alignment with Blinkit’s fast-paced environment.
The candidate applied for the SDE1 position at Blinkit and went through a 3-round hiring process, but was eliminated after the system design round due to lack of preparation.
