Technical cards
Markets, derivatives, rates, risk, statistics, code, SQL, ML, M&A, answered out loud, in spaced repetition.
Free platform · English and French
Markets, data and deals run on code. So does the interview.
QuantPad is where you train for a quant, data or M&A seat by writing real code that is graded as you go, from your first spread to a vol surface, a model in production or an LBO.
Parametric VaR · MSFT
from scipy.stats import norm r = prices[prices["symbol"] == "MSFT"] \ .sort_values("day")["close"].pct_change().dropna() result = -(r.mean() + norm.ppf(0.05) * r.std(ddof=1)) * 100
Correct · 95% VaR: 0.8594%

Three worlds
Pick the seat you want. The route follows.
Each world has its own tracks, exercises and career ladder, and they share the same engine: what you read in a lesson is a graded exercise five minutes later.
Data science
- SQL, pandas, NumPy, SciPy, scikit-learn on real tables
- Data analyst, data scientist, data architect ladders
- A/B tests, cohorts, validation without leakage
Markets & quant
- Pricing, volatility, risk, microstructure, execution
- Backtests in seven languages, on real prices
- Market-making game and timed duels
M&A & private equity
- DCF, comparables, accretion, LBO models
- The Deal Room: value, structure, bid
- Real deals explained, from the SPA to antitrust
The Lab
Real data tools, graded on the result.
Write the code, run it on the shared datasets, and the answer is checked to four decimals. Python and SQL run in your browser; Julia and C++ run on the QuantPad runner.

Inside the LabA/B test on revenue · Welch
from scipy.stats import ttest_ind rev = (users.set_index("id")[["variant"]] .join(payments.groupby("user_id")["amount"].sum()) .fillna({"amount": 0})) # non-payers count a, b = (rev.loc[rev.variant == v, "amount"] for v in "AB") t = ttest_ind(a, b, equal_var=False) result = [t.statistic, t.pvalue]
Correct · t = -1.5947, p = 0.1116
