Three key factors for fintech employer selection: regulatory risk appetite, technology maturity, and compensation structure. Regulatory risk: companies operating as licensed NBFCs or banks (Paytm Payments Bank before RBI action, Slice's banking aspirations) have higher regulatory volatility. Payment gateways (Razorpay, PayU) have lower direct regulatory exposure. Technology maturity: Zerodha and Razorpay have mature, modern tech stacks built from greenfield. Paytm and Angel One have legacy systems being modernised: different learning experience (legacy navigation vs greenfield design). Compensation structure: private companies (Razorpay, Zerodha, CRED) offer ESOPs with uncertain liquidity timelines. Listed companies (Paytm, Angel One) offer listed RSUs with immediate post-vesting liquidity. What fintech interviews specifically test beyond standard coding: payment domain concepts (idempotency, settlement cycles, T+2 clearing), regulatory awareness (PCI DSS for card data, SEBI rules for brokers), and how to build fraud-resilient systems. Domain knowledge differentiates candidates at the same DSA level: a candidate who understands UPI transaction flows, mandate-based recurring payments, and the role of NPCI has a significant edge at PhonePe or Razorpay.
