Software Engineer (Backend/Full Stack)

PhonePe’s interview process typically starts with an online coding assessment, followed by a technical interview that tests data structures, algorithms, and language‑specific knowledge. Candidates then face a system design interview focusing on scalability, consistency, and performance of payment systems, and finally an HR round that evaluates cultural fit and communication skills. Preparation should include solving medium‑hard coding problems, revisiting core system design concepts, and practicing clear articulation of solutions.

PhonePe promotes a collaborative and innovative work culture where engineers are encouraged to experiment and own end‑to‑end solutions. The company offers clear career progression, regular learning sessions, and a healthy work‑life balance supported by flexible timings and remote‑friendly policies.
