Interviews Weren't Built For You. Prepdock Is.

We know you're brilliant. But sometimes, the pressure of a live interview makes it hard to show it. Prepdock is designed to be your invisible support system.

Your AI Pair Programmer

Instead of just giving answers, Prepdock provides hints and suggestions like a real teammate to help you articulate your thoughts.

Humanize, Don't Memorize

Fine-tune your STAR-method stories and behavioral answers to sound authentic, not robotic. Let your true self shine.

Truly Invisible Support

Our overlay is invisible to screen-sharing. Use 'Invisible Typing' to jot down private notes that only you can see.

Your Career, Your Context

Upload your resume, job descriptions, and notes to get hyper-relevant, personalized advice tailored to your specific goals.

True Invisibility

No windows. No noise. Just presence.

PrepDock runs silently in the background during interviews — capturing screen and audio without disrupting your flow. There's no interface to manage, no pop-ups to close, and no clicks required. Just you, the interview, and contextual support when you need it.

Zero visible interface
Non-intrusive audio capture
Background screen recording
Seamless candidate experience

Everything happens behind the scenes. You stay fully present.

Built for Pair Programming

Example Response
def fizzBuzz(n: int) -> List[str]:
result = []
for i in range(1, n + 1):
if i % 3 == 0 and i % 5 == 0:
result.append("FizzBuzz")
elif i % 3 == 0:
result.append("Fizz")
elif i % 5 == 0:
result.append("Buzz")
else:
result.append(str(i))
return result

What it misses:

  • • No context or problem understanding
  • • No clarification questions
  • • No room for collaborative thinking

PrepDock AI

Context-aware response

Context-Aware
Structured Approach
Understanding:

This is the classic "FizzBuzz" problem: given an integer n, return a list of strings for numbers 1 to n where multiples of 3 are replaced with "Fizz", multiples of 5 with "Buzz", multiples of both with "FizzBuzz", and all others with the number as a string.

Plan:
  • Loop from 1 to n
  • Use modulo to check divisibility
  • Append correct string to answer list
💬

Your Turn: Should I assume n ≥ 1, or would you like to add constraints?

If so, I'll write the implementation next. Let me know if you want extra logging or restrictions!

✨

What makes it unique:

  • • Breaks down problems step-by-step
  • • Asks clarifying questions proactively
  • • Maintains collaborative thinking flow
  • • Provides structured guidance, not just code

Experience pair programming that thinks with you, not just for you.

Behavioral Tuning

Response Clarity25%

GENERIC GPT

Dramatic & Rambly

Example Response
"Oh, disagreements. Yeah, they're bound to happen when you're working in a team, right? I remember this one time at AMD. We were in the middle of a sprint and there was this heated debate about the best way to implement a new feature for our telemetry portal. I mean, everyone had their own ideas, and things got a bit tense... Honestly, it was more about finding common ground. We ended up going with a hybrid approach, and it worked out."

Clarity Score

25%

Too vague to be memorable
💬
This response feels scattered and unfocused. It rambles without clear stakes or resolution.

Highlights

  • •Rambles with filler words ("Yeah", "I mean")
  • •Vague stakes and unclear conflict
  • •No specific technical details

Could Improve

  • •Too many filler words and vague language
  • •No clear conflict or resolution

The more context you provide, the more PrepDock sounds like you — but better.
