PhonePe SDE hiring runs on an interview process, not a single written exam — an online assessment (often on CodeSignal), followed by a loop of coding, machine coding (LLD), system design (HLD), and behavioral rounds. The exact mix shifts with role level and years of experience — the outline below is the pattern that shows up most consistently across recent (2025–2026) candidate reports.
Typical PhonePe SDE interview process
| Stage | What it tests | Typical length |
|---|---|---|
| Online Assessment | 2–4 coding questions (medium to hard), sometimes on CodeSignal | 60–90 min |
| DSA / Live Coding Round(s) | 1–3 data-structure-heavy problems, evaluated on approach and complexity as much as the final answer | 45–60 min |
| Machine Coding (LLD) | Build a working class design for a real system from scratch, with a follow-up review on concurrency and extensibility | 90–120 min + review |
| System Design (HLD) | From SDE-2 upward — a full architecture discussion for a fintech-flavored or consumer-scale system | 45–60 min |
| Resume / Hiring-Manager Round | Past project decisions, team fit, behavioral questions, and compensation discussion | 45–60 min |
Coding rounds don't stop at DSA — candidates consistently report that machine coding (LLD) and system design (HLD) carry equal or greater weight from the SDE-2 level onward. See the Behavioral & Culture-Fit Questions section to prepare for the softer side of the loop too.
Process varies by level and team. Candidates with 1–3 years of experience see a leaner loop weighted toward DSA and a behavioral round; candidates at SDE-2 and above regularly face both a dedicated LLD machine-coding round and a separate HLD round, often on payments- or settlement-flavored systems.
Prepare each track on its own terms: DSA, LLD, System Design (HLD), and Behavioral & Culture-Fit prep.
