I applied online. I interviewed at Refyne in Jul 2024
Interview
The process had 3 rounds:
Round 1 (Manager) – Mix of HLD + LLD design questions.
Round 2 (SDE-2) – Deep dive into LLD and object-oriented design.
Round 3 (DSA) – Problem-solving on algorithms and data structures.
Overall, the process was structured and balanced between design and coding.
