Software Development Engineer

Candidates typically face a timed online coding test covering data structures, algorithms, and basic aptitude, followed by a technical interview that dives deep into Java, micro‑services, and system design. The HR round focuses on cultural fit and career aspirations. Preparing with mock tests and revisiting core backend concepts greatly improves success chances.

Juspay promotes a fast‑paced, collaborative environment where engineers are encouraged to experiment and ship features quickly. The company offers regular learning sessions, mentorship programs, and a transparent feedback loop, ensuring a good work‑life balance despite the high‑impact nature of the product.

Undergraduate degree (B.Tech/B.E.) in Computer Science, Information Technology, Electronics & Communication or related engineering streams; minimum aggregate 60% (or equivalent CGPA); graduating batch 2023‑2025; no active backlogs at the time of joining; strong programming fundamentals and problem‑solving skills.

Round 1: Online aptitude and coding test (platform‑based, 60‑90 minutes) → Round 2: Technical interview (coding, system design, and problem‑solving) → Round 3: HR round (cultural fit, motivations, and compensation discussion)
