The gap is real.

Bootcamps optimise for breadth across Python, pandas, viz, ML. SQL depth gets 2 weeks. Interviews want 3 years of it.

Your cohort covered

SELECT, WHERE, basic filters
INNER JOIN on 2 tables
GROUP BY with COUNT / SUM
Maybe one CASE example
A capstone project SQL query

Interviews actually ask

Window functions (RANK, LAG, running totals)
Correlated subqueries and CTEs
3+ table JOINs with self-joins
Gap analysis, cohort retention, top-N per group
Write cold, on a whiteboard, in 15 minutes

The Coach targets the gap directly.

Pick the FAANG Interview Prep goal. The coach reads your skill radar from your first few solves, identifies your weak spots, and drills them with mastery checks that require fresh solves, not recognition.

Finds your gaps

First few solves calibrate the radar. You see which of the 10 canonical skills you're weakest on.

💪

Produce, don't recognise

Mastery checks require fresh solves. No question bank you can grind answers to.

⏱️

Mock interview mode

Timed, scored, pressure-simulated. Matches Meta / Google / Amazon phone screen format.

⏳

Spaced retrieval

Retrieval checks schedule a cold re-solve a day after each lesson. That's how it sticks for the interview.

Before you click

My bootcamp already covered SQL. Is this repetitive?

No. The adaptive coach reads your skill radar from your first few solves. If you're already strong at the basics your bootcamp covered, those steps auto-skip. It routes you to the depth that bootcamps don't have time for — window functions, correlated subqueries, CTEs, top-N patterns.

How long until I'm interview-ready?

It depends on how deep your cohort went and how fast you practice. Users coming out of a 12-week data bootcamp typically close the window-function + subquery gap in 3–4 weeks of steady practice, and pass their first FAANG-tier phone screen within 6 weeks.

Does it cover FAANG-style interview questions?

Yes. FAANG Interview Prep is a dedicated goal track with 200+ questions modelled on the exact patterns Meta, Google, Amazon, Apple, and Netflix ask in phone screens and onsites. Plus timed mock-interview mode.

Is it really free?

Yes. All challenges, the adaptive coach, skill radar, mock interviews, and 10 AI tutor calls per day are free. No credit card. Pro unlocks unlimited AI tutoring plus Hard challenges and the full mock-interview bank if you want it later.
