PICTURE THIS: A SENTENCE BECOMES TOKENS

The model does not read letters like humans. It reads these pieces, then predicts the next one.

Simple meaning

XSS exfiltrates tokens, mixed content loads bad scripts, and verbose errors reveal internals.

WHY — Security instead of guessing?

Why interviewers care about Security:

This is a process

question about Security.

Panels listen for order,

trade-offs, and what you would actually do on a Frontend project - not buzzwords.

Stay structured

Name the idea, why it exists, then one short example.

Close cleanly

End with when you use it and one common pitfall.

STEPS — What happens with tokens?

Before the model can read a sentence, it goes through these steps:

  1. 1
    XSS exfiltrates tokens, mixed

    content loads bad scripts, and verbose errors reveal internals.

  2. 2
    Token IDs

    HTTPS encrypts the wire

  3. 3
    Embeddings

    it does not fix XSS.

  4. 4
    I treat CSP and

    safe rendering as mandatory.

  5. 5
    Next token

    The model scores what should come next.

  6. 6
    Decode

    IDs turn back into readable text.

Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.

Key takeaway

XSS exfiltrates tokens, mixed content loads bad scripts, and verbose errors reveal internals. HTTPS encrypts the wire
