Intercontinental Exchange Lead Developer - Java/Springboot - Europe/Americas interview questions

Interview Process & Prep Guide Step 1 – Apply Online Someone from Talent Acquisition schedules a 30-minute call to explain the role and ask for your salary expectations. If that goes well, you’ll get a 1-hour interview with the manager. Round 1 – Manager Interview You’ll likely meet a 30+ years experienced manager who knows all the modern buzzwords but may not be very familiar with technologies from the last decade. The conversation is mostly about: Explaining what you’ve worked on in the last 6 months Walking through technologies and design decisions Be ready to explain things at a very fundamental level, because questions may include gems like: “How did you figure out which class or method had the bug?” Round 2 – Technical Interview This round includes: The same manager Two lead developers They again ask about your recent work, but go slightly deeper into: Libraries used Implementation decisions Then the manager pulls out a couple of classic Java problems from the internet and asks you to review or explain them. Thankfully, it’s usually discussion-based rather than live coding. After the Interview I sent a thank-you email the same day and a follow-up a week later. A few days after that, I got the classic “moving forward with other candidates” message. If you’re selected, you’ll probably hear much sooner. Preparation Tips The environment appears to be a carefully preserved time capsule: COBOL applications still exist No cloud Waterfall development Separate offshore QA team Separate DBA team writing queries What to study: Basic HackerRank / LeetCode problems Pre-Java-8 style solutions Basic Spring awareness What not to overprepare: Modern architecture, cloud-native design, reactive frameworks, or anything invented in the last decade. Final Advice If you want the job, adapt to the technological timeline of the company. Sometimes success in interviews isn’t about knowing the latest technology — it’s about not being several generations ahead of the conversation.
