“I know you’re a tech company and you’re hiring engineers.”
Why it’s bad:
It shows zero research and zero interest. If you didn’t bother to Google them, why should they bother with you?
Good answer:
“I know you’re building [specific product], you recently [recent news/launch], and your engineering blog mentioned [specific technical challenge]. I’m particularly interested in how your team handles [relevant area].”
Why it works:
You show you’ve done real research. Referencing specific details proves genuine interest, not just job-hunting.
Key takeaway:
Research the company before every interview. Mention specifics: their product, tech, or recent news. Generic answers get generic rejections.

Face ID creates a mathematical representation of your face stored in a secure hardware enclave on the device, and all matching happens locally.
Explain like I’m 5 years old:
1. Face ID takes a special picture of your face using invisible dots.
2. It turns that picture into a math equation.
3. The equation is stored in a locked vault on your phone.
4. When you look at the phone, it makes a new equation and compares.
5. If they match, the phone unlocks. Apple never sees your face.
Correct explanation (engineer-level, simplified):
Face ID uses a TrueDepth camera that projects over 30,000 infrared dots onto your face to create a depth map. This 3D map is processed by a neural network on the device’s Neural Engine, which converts it into a compact mathematical representation (a feature vector). This vector is encrypted and stored in the Secure Enclave, a hardware-isolated coprocessor with its own encrypted memory.
During authentication, a new scan is compared against the stored vector. The comparison produces a similarity score; if it exceeds the threshold, authentication succeeds. The entire process (capture, inference, comparison) happens on-device. The Secure Enclave never exposes the stored biometric data to the OS, apps, or network.
Key engineering trade-offs:
- Security vs convenience (false accept vs false reject rates)
- On-device processing vs cloud-based accuracy
- Hardware requirement vs device compatibility
- Privacy vs feature richness
Why this matters:
Biometric authentication is the future of identity verification. Understanding how it maintains privacy through hardware isolation and on-device ML helps you appreciate the depth of mobile security architecture.

“I prefer working alone. I’m more productive that way.”
Why it’s bad:
Engineering is a team sport. Preferring isolation raises concerns about collaboration and communication.
Good answer:
”I do my best deep work alone, but I value team collaboration for design decisions, code reviews, and brainstorming. I like a balance: focus time for building, team time for aligning.”
Why it works:
You acknowledge both needs without being extreme. It shows you’re adaptable and self-aware.
Key takeaway:
The right answer is balance. Show you can do deep work AND collaborate effectively.

Explain like I’m 5 years old:
1. Postman is allowed to ask freely.
2. Browsers must follow safety rules.
3. Some requests are blocked to protect users.
4. The server must say “this is allowed.”
5. Otherwise the browser stops it.
Correct explanation (engineer-level, simplified): Browsers enforce CORS to prevent malicious websites from accessing sensitive data. When a web app makes a cross-origin request, the browser may send a preflight OPTIONS request to verify what is allowed. If the server does not explicitly permit the origin, headers, or methods, the browser blocks the request locally.
Postman does not enforce these rules because it is not acting on behalf of an untrusted web page. This means the API itself is often working correctly, but the browser is intentionally preventing access for security reasons. Authentication, cookies, HTTPS requirements, and headers behave differently in browser contexts.
Key engineering trade-offs:
* Security vs developer convenience
* Controlled access vs open APIs
* Browser safety vs flexibility
Why this matters:
Many “API bugs” are actually browser security features. Understanding this avoids misdiagnosing backend issues.

Compression removes redundancy, not meaning.
Explain like I’m 5 years old:
1. Imagine writing the same word many times.
2. Instead of repeating it, you write a shortcut.
3. The message stays the same.
4. It takes less space.
5. Repeating things shrink well.
Correct explanation (engineer-level, simplified):
Compression algorithms analyze data to find repeated byte patterns and replace them with shorter references. Text files, logs, and raw datasets often contain high redundancy, making them compressible. Already-compressed formats like videos or images usually shrink very little because redundancy has already been removed.
Zipping trades CPU time for reduced storage size and faster network transfers. During decompression, the original byte stream is reconstructed exactly, which is why zip compression is considered lossless. The effectiveness depends entirely on the structure of the data.
Key engineering trade-offs:
* CPU usage vs storage savings
* Compression time vs transfer speed
* Battery cost vs network cost
Why this matters:
Compression lowers bandwidth usage and storage costs. At scale, this directly impacts performance and infrastructure spending.

Courier apps send periodic GPS updates to a backend, which distributes controlled, scoped updates to the customer app.
Explain like I’m 5 years old:
1. The courier’s phone checks where they are.
2. It tells a big computer in the middle.
3. That computer tells your phone, “Your courier moved a little.”
4. Your phone draws the movement smoothly so it looks alive, not jumpy.
Correct explanation (engineer-level, simplified)
- The courier app reads GPS using OS location service.
- Location updates are sent every N seconds (or distance-based.
- Data is sent via HTTP or persistent connection (WebSocket.
- Backend validates accuracy, freshness, and assignment
- Updates are throttled to reduce battery drain and server load
- Locations are stored in fast in-memory or time-series stores
- Customer app subscribes only to its assigned courier
- Real-time delivery uses WebSocket / SSE / Pub-Sub systems
- UI interpolates between points to hide GPS jitter
- Fallback polling is used when real-time connections fail
Key engineering trade-offs:
- Update frequency vs battery consumption
- Real-time accuracy vs network reliability
- Scale: tens of thousands of moving couriers
- Privacy: strict access control per order
- UX: perceived smoothness over raw accuracy
Why this matters:
Most “real-time” systems are controlled illusions.
Good engineering is about managing constraints, not chasing perfect live data.
