Swiggy Frontend Engineer Interview Experience

The Swiggy Frontend Engineer interview process was extensive and technically challenging, spanning five rounds. The initial round was an online assessment focusing on practical frontend skills with tasks in React and CSS. Subsequent rounds included technical interviews addressing core JavaScript concepts, system design for a real-time application, and a machine coding round with various tasks. The overall impression is that the interview process at Swiggy thoroughly evaluates both technical capabilities and cultural fit.
