  • Two Coding Rounds Plus a Hotel Reservation System DesignLead Bank · Software Engineer · Onsite · Jul 2026

    The first coding round was similar to what people describe online — it's the one where you treat it as a stock ticker + date + price log. The interviewer guides you step by step, so you can pretty naturally arrive at the solution. Here's roughly what my code looked like: System design: the classic hotel reservation system design that shows up online a lot. Though there was a twist — the interview…
