Nium’s Coding Interview Be Like...
Hey there, future fintech innovators!
If you’re considering a career in engineering and technical services with a global leader in real-time payments, then look no further. This is your “top tips” guide for joining #TeamNium.
Our engineering interviewing approach is quite different from your “usual” tech interviews – it’s specifically tailored for the fast-paced and multifaceted world of fintech.
1. Tackling Multiple Problems – It’s More Realistic.
In our interviews, you won't be stuck on just one mammoth problem. Instead, you'll face several smaller, distinct challenges. Here's why we do it this way:
- Variety is the Spice of Life: This format lets you show off a wider range of skills – from crunching algorithms to optimizing code and everything in between.
- Real-World Vibes: Each problem is a mini version of the actual challenges we tackle at Nium. It's about seeing how you’d fit into the day-to-day problem-solving we do here.
- Juggling Skills are Key: Managing multiple tasks is part of our daily grind. How you handle these varied problems gives us a glimpse into your time management and adaptability.
2. Data Structures We Love (And Some We Don’t).
Alright, let’s talk about data structures. In fintech, not all data structures are created equal and here’s how we map out ours:
- Nium Go-To's: We lean heavily on arrays, strings, hash tables, trees, and graphs. Why? They’re the bread and butter of fintech applications. For instance, modeling payments using a graph can be a game-changer in anti-money laundering and fraud detection.
- What We Skip: We usually don’t delve into overly complex data structures like Fibonacci heaps or other specialized tree structures. While they have their place, they aren’t typical in the day-to-day work we do at Nium. We prefer to focus on what you’ll use in the job.
3. Testing: Where the Rubber Meets the Road.
Testing isn’t just a checkbox for us – it’s where your code proves its mettle. Fintech is all about precision and reliability. Can your code handle edge cases? Is it bulletproof security-wise? That’s what we’re looking to find out.
4. Hints: Not Giveaways, but Nudges.
Stuck on a problem? Don’t worry, we’ve all been there. Our interviewers might drop a hint or two, not to hand you the solution, but to nudge your thought process in the right direction. It’s about seeing how you pivot and adapt.
5. Why #NiumCares About Your Experience.
Your interview with us is as much about you getting to know us as it is about us getting to know you. We want you to walk away with a real sense of our #SimplyBetterTogether culture – whether you join us or not. We strive for respect, support, and constructive feedback.
