Section by section, with a worked example

Every example below is generated by Outcry, drawn from the same generator that section runs during the timed sitting. None of it is Jane Street's own material.

A. Strategy and product

20 items in 60 minutes, multiple-choice and typed short answer mixed. Unit economics, market reasoning, Fermi estimates, tables, statistics and product tradeoffs.

In this Outcry section: 20 items in 60 minutes, averaging 180 seconds per item. Wrong answers receive no marks and carry no deduction. Unanswered items score zero. Correct-answer weights are shown on the questions. These are the mock’s rules.

Example 1

A platform settles $700m of notional a year and charges 8 basis points on it. What is the annual revenue, in millions of dollars?

Answer 0.6

8 bps is 0.08%, so $700m × 8/10,000 = $560,000 a year, which is 0.6 million.

Example 2

Variant       Users   Conversions
A (control)    7300           285
B              2000            94

How much higher, as a percentage, is variant B's conversion rate than control A's, in relative terms?

Answer 20.4

A converts at 285/7,300 = 3.9% and B at 94/2,000 = 4.7%. The relative lift is (4.7 − 3.9) ÷ 3.9 = 20.4%. The gap in percentage POINTS is 0.8, which is a different figure.

Example 3

Plate  16  18  19
Mill   11  17  19
Trim   12  16
Weld   12  17  19

One maintenance job is booked. The list above gives every possibility as a workshop and a slot number. Ana is told the workshop only, Ben is told the slot only, and both know the list. Ana says: "I do not know which job it is, and I can tell that Ben does not know either." How many of the listed jobs are still possible after that statement?

Answer 5

Ana's second clause is the working part. Ben would know the job outright if his slot appeared only once on the list, so for Ana to rule that out, every slot paired with her workshop must appear at least twice. Checking each workshop against the 11 entries leaves 5 jobs: Trim, slot 12; Trim, slot 16; Weld, slot 12; Weld, slot 17; Weld, slot 19. The first clause alone only drops workshops that appear once, which is the weaker cut.
