Train for RFIC interviews one question at a time.
A guided question maze for analog and RFIC candidates. Short drills. Follow-up questions. Clear feedback.
A prep ladder, not a question dump.
The product should feel simple while you use it: one question, one answer, one next step. Under the hood, the ladder gets harder as your reasoning improves.
1. Start simple
Begin with fundamentals, then move through MOS devices, small-signal models, op-amps, feedback, RF basics, and RFIC blocks.
2. Explain
Interviews reward reasoning. Each drill pushes you to explain intuition, equations, assumptions, and tradeoffs.
3. Level up
Miss a concept and the next step becomes targeted: review, follow-up question, or a harder variation.
The actual product is a maze.
Not a long page of text. Candidates move through short RFIC interview moments: answer, explain, get feedback, unlock the next question.

What buyers are getting.
The first beta is for people preparing for RFIC, analog, or mixed-signal interviews who need practice talking through circuits under pressure.
Question tracks
- MOS fundamentals
- Current mirrors and biasing
- Differential pairs
- Feedback and frequency response
- Noise, linearity, and matching
- LNA, mixer, oscillator, PLL basics
Interview skills
- Derive without freezing
- Explain design tradeoffs
- Recover from follow-ups
- Connect equations to circuits
- Talk through measurement and debug
Best for
- MS / PhD students
- New grads
- RFIC / analog candidates
- Engineers returning to interviews
- Candidates targeting high-bar hardware teams
Beta offer.
Early users help shape the question ladder. The first cohort gets lower pricing than the public launch and direct influence over the tracks we build first.
- Expected beta: $49–$99 after validation
- Initial access: staged RFIC/analog question ladder
- Goal: help candidates practice the questions they actually miss
