💻 Software Engineer Interview Questions -Day 13

❓ Today’s question comes from a live coding interview.

You are given a pricing service with an intermittent bug that only appears during peak traffic.

A product normally shows the correct price, but sometimes it shows the price and promotion of a different product.

The problem cannot be reproduced with a single request or in the low-traffic acceptance environment.

Your task is to:

-find and explain the root cause
-identify possible edge cases
-investigate whether concurrency is involved
fix the bug
-consider whether your solution will scale under high traffic

The interesting part isn’t just fixing the code, it’s how you investigate and reason about the problem.

💭 If you got a live coding question like this, how would you start thinking about it?

My Day 13 question is actually one of these! 🫰

[Merve Türk @mtmturk]

I’m so excited! 🫣✨

This week, I have interviews with two of my dream companies in the Netherlands. The interview processes include live coding and system design. 🚀💻

Once the entire interview process is complete, I’ll share my experience and all the details here. 📝

Wish me luck! 🍀🤞

💻 Software Engineer Interview Questions-Day 12

Let’s talk about failure scenarios. 👀

❓ What happens if your message broker goes down?

Imagine your service needs to publish an event, but the broker is temporarily unavailable.

How would you handle it without losing data or processing the same message twice?

Next week, I have another interview in the Netherlands. 🇳🇱
The company invited me to a face-to-face session, which will include live coding and system design.

I’m already excited! 👍😬
After the sessions, I’ll share the details here.

If you’ve had a similar interview, I’d love to hear your experience and advice. 🤝

Big Tech interviews don't test 500 completely different DSA ideas. 📌

The same patterns keep coming back in different disguises.

If you're preparing for software engineering interviews, learn to recognise these patterns instead of memorising solutions.

Here are the ones I'd master first 🧵👇

[Merve Türk @mtmturk]

I have a question for you ❔

How do you stay calm and avoid blanking out during interviews, especially during live coding WITHOUT AI ? 👀💻

What helps you manage your nerves and think clearly under pressure?

I’m curious to hear what works for you. 🧠✨

I think this is a really useful repo for learning SYSTEM DESIGN, so I’m leaving it here for future reference. 💻
