I keep hearing about ‘browser sandboxing’ but I’m not sure I understand it. Can someone explain in simple terms why interview platforms can’t see what’s running on my computer?
Browser Sandboxing Explained Simply
Browser sandboxing is a security feature built into all modern browsers (Chrome, Firefox, Safari, Edge). Here’s what it means:
The Sandbox Concept:
Imagine every browser tab as a sealed room. The website in that tab can do whatever it wants inside the room, but it cannot:
- Open the door and walk into other rooms (other applications)
- Look through windows to see what’s outside (your desktop)
- Listen through walls to hear other conversations (other processes)
Why This Exists:
This security exists to protect YOU. Without sandboxing:
- Malicious websites could read your files
- Ads could monitor everything you do
- Any webpage could install malware
What This Means for Interviews:
Interview platforms operate under the same restrictions as any website. They cannot break out of their sandbox to see:
- What applications you have open
- What’s in your system’s memory
- What processes are running
- What’s on parts of your screen they haven’t been given access to
Interview Coder operates entirely outside this sandbox, making it invisible to any browser-based interview platform.
