Got your Citadel test link? Try the Wonderlic and the FCAT below in the real format, then read how each one works, how long you get, the coding test for software and what comes after.

Key facts
- Which tests: The Associate Program (investing) sends the Wonderlic cognitive test, and in the full-time 2027 process the FCAT modeling test with it. Software applicants get a HackerRank coding test.13,14,17,18
- Wonderlic: Multiple-choice questions on simple math, logic, word meaning, spatial reasoning and patterns, on one 12-minute clock, getting harder as you go. The summer 2027 internship email listed a 15-minute online assessment.5,6,15,12
- FCAT: Build and link an income statement, balance sheet and cash flow statement in a web spreadsheet, on one clock. In the full-time 2027 process it came with the Wonderlic and ran 45 minutes.13,14,16
- Time to finish: In the full-time 2027 process the Wonderlic and FCAT links came straight after applying for some and a few days later for others, with one week to finish both.13
- Finishing: Wonderlic does not expect you to answer all 50 in 12 minutes. Its scoring weights each question by difficulty and accounts for guessing, so blind guesses are unlikely to help: if you think you know the answer, mark your best choice and move on.5,6,7
- Calculator and Excel: The Wonderlic allows no calculator, dictionary or other resources. The FCAT runs in its own web spreadsheet: most Excel shortcuts do not work and not every Excel formula is available.6,7,13,16
- Software: Two coding problems, medium to hard. Hidden test cases check edge cases and speed, and the timer keeps running if you lose your connection.18,9,10
- Passing: Wonderlic sets no universal pass mark: the employer compares your result with what predicts success in the role. In the full-time 2027 process, an FCAT whose balance sheet did not fully balance still went through to the next round.8,13
Citadel Securities, the market maker, is a separate firm with its own page. This page covers Citadel's tests for the Associate Program and software; quant research and trading tests are not covered here.4,11

What the Citadel online assessment looks like
The invite
For the Associate Program the tests come after you apply. In the full-time 2027 process the links came straight after applying for some and a few days later for others, and a referred applicant who had a business development call first got them as soon as they applied. There was one week to finish both. The summer 2027 internship email listed a 15-minute online assessment before the recruiter interview.13,12
The Wonderlic
Fifty multiple-choice questions on one 12-minute clock: dates, analogies and opposites, number series, short word problems, logic statements, charts and shapes. They get harder as you go. No calculator, dictionary or other resources. Wonderlic does not expect you to finish, weights each question by its difficulty and accounts for guessing, and advises against skipping around: if you think you know the answer, mark your best choice and move on.5,6,7,15
The FCAT
One model, not a list of questions. You build the income statement, balance sheet and cash flow statement so they tie, in a web spreadsheet on one clock (45 minutes in the full-time 2027 process). Most Excel shortcuts do not work and the formula conventions differ from Excel's. Expect a segment-by-segment revenue build, then ratio work and a simple valuation at the end that count toward the full score. No camera is needed.13,14,16
The coding test for software
Software applicants get a HackerRank test: two problems, medium to hard. Run Code checks your code on your own input; hidden test cases check edge cases and performance. The timer keeps running if you go offline, and you can log back in while time is left.18,9,10
After the tests
In the full-time 2027 process a 45-minute business development round came next, then interviews with investment professionals; for summer 2027 a Zoom interview with a recruiter followed the test. Software moves to a 45-minute video round on coding and your reasons for Citadel.13,14,12,4
How to spend the clock on the FCAT
- Read the assumptions About 4 min
- Find each driver, the forecast years and the ratio definitions before you type anything.
- Revenue and income statement About 12 min
- The segment revenue build, costs, interest and tax, copied across the years.
- Working capital and cash flow About 12 min
- Receivables, inventory and payables, capex and depreciation, then cash flow.
- Balance sheet and check About 9 min
- Link cash and equity, then make the check row read zero in every year.
- Ratios and valuation About 8 min
- Ratios on the sheet's definitions, then the simple valuation.
The split is Intervyo's advice, not Citadel's. It follows the order the model ties in, and leaves time for the balance check, the ratios and the valuation that count toward the full score.13,16
Before you start the tests
- Plan both Associate Program tests well inside the week, one slot each, with time to rest between them.
- Wonderlic: pen and paper, no calculator, and 12 minutes with no interruptions.
- Try Wonderlic's free timed practice questions to feel the pace of about 14 seconds a question.
- FCAT: a laptop with a full keyboard and a mouse, and an hour clear.
- Build a three-statement model from a blank sheet in under 40 minutes, without keyboard shortcuts.
- Know your ratios, and read each definition on the sheet before you use it.
- Software: timed medium and hard coding problems in the language you will use.
- A stable connection: the clock keeps running if you drop.
The sections, one by one
Wonderlic says its cognitive test covers simple math, basic logic, language comprehension, spatial reasoning and pattern identification, and gets harder as it goes. The FCAT is one model with its own outputs: the statements, then ratios and a value.5,6,13,16
- Dates: Pick the earliest or latest of five dates that differ by a digit.
- Analogies and opposites: Complete a word pair, or find the word opposite in meaning.
- Number series: Find the next number in a sequence.
- Word problems: Short math on prices, rates and shares, without a calculator.
- Logic and shapes: Decide whether a conclusion follows, or work out which shape fits.
- Three-statement model (FCAT): Forecast revenue, costs, working capital and cash so the balance sheet balances.
- Ratios and valuation (FCAT): Ratios on the sheet's own definitions, then a simple value.
Here is each test as it appears in Intervyo: the Wonderlic, one question to a screen under one 12-minute clock with Previous and Next, and the FCAT, a web spreadsheet with tabs for the assumptions and each statement under one clock (45 minutes, as in the full-time 2027 process), with your answers typed in a panel beside it. The FCAT's layout is Intervyo's own setting; its task, clock and web spreadsheet follow the accounts of people who sat it. Each block says what the test is checking and how to do it well.5,6,13,16
1.Wonderlic cognitive test50 questions, 12 minutes

Fifty multiple-choice questions on one 12-minute clock, one to a screen: dates, analogies and opposites, number series, short word problems, logic statements and shape questions. They get harder as you go, and there is no calculator, dictionary or other help.5,6,7,8
What it measures: How quickly you take in new information and reason through it: simple math, basic logic, language comprehension, spatial reasoning and spotting patterns.
How to answer it well
- 1Bank time on the quick types. Dates, opposites and analogies take seconds, so answer them at once.
- 2Keep to about 14 seconds a question. If a word problem needs more than a line of working, mark your best choice and go on.
- 3Read every word of the question. Many mistakes come from misreading: earliest for latest, or opposite for closest.
- 4Do the sums in your head or on paper. There is no calculator, and only a few questions need real arithmetic.
- 5Do not plan a second pass. Wonderlic advises against skipping around, and many people never reach question 50.
2.FCAT modeling test45 min (full-time 2027)

One model rather than a list of questions. You build the income statement, balance sheet and cash flow statement so they tie, in a web spreadsheet on one clock (45 minutes in the full-time 2027 process). Most Excel shortcuts do not work, not every Excel formula is available, and the conventions differ from Excel's. Expect a segment-by-segment revenue build, then ratio work and a simple valuation that count toward the full score. No camera is needed.13,14,16,12
What it measures: Whether you can build a model that ties under a clock: revenue drivers, costs, working capital, a cash flow that feeds the balance sheet and a balance sheet that balances, then ratios and a value on the stated definitions.
How to answer it well
- 1Build in order: revenue, costs, the income statement, working capital, cash flow, then the balance sheet. A model that ties with rough lines beats a detailed one that does not balance.
- 2Leave time to balance. A balance sheet still out when the clock ends costs marks even when everything else is right.
- 3Read each ratio's definition before you use it. One ratio wanted a point-in-time denominator where many people would use an average.
- 4Type a formula once and copy it across the years rather than keying each cell.
- 5Practice in a plain web spreadsheet without shortcuts, so slow navigation does not eat the clock.
Best guessSummer 2028 internship applicants may get the Wonderlic alone: the summer 2027 internship email listed one 15-minute online assessment, and both dated FCAT accounts come from the full-time process. Prepare for the FCAT anyway.
Example questions and how to answer them
Dates"Which of the following is the latest date? (a) Mar 4, 1968 (b) Mar 14, 1986 (c) Feb 28, 1986 (d) Mar 9, 1986 (e) Dec 31, 1968"6
- 1Check the question word first: latest or earliest.
- 2Compare the years and cross out every option in the wrong one.
- 3Among what is left, compare the months, then the days.
- 4Watch for swapped digits: 1968 and 1986 look alike at speed.
Tip: Written by Intervyo in Wonderlic's date format. Not a Citadel item. These should take under 10 seconds, which buys time for the word problems.
Example answer, written by Intervyo (not a real candidate)
(b) Mar 14, 1986. The two 1968 dates go first. Of the 1986 dates, March beats February, and the 14th is later than the 9th.
Word problems"A team of 12 analysts covers 180 stocks, split equally. Three analysts leave and coverage stays at 180 stocks, split equally among those who remain. How many stocks does each remaining analyst cover?"5,6
- 1Find the number that stays the same: 180 stocks.
- 2Work out who is left: 12 minus 3 is 9.
- 3Divide once. The starting 15 a head is a distraction.
- 4Sense-check: fewer people, so more stocks each.
Tip: Written by Intervyo in the word problem format. Not a Citadel item. There is no calculator, so look for the one division that answers it.
Example answer, written by Intervyo (not a real candidate)
20. 180 stocks shared among 9 analysts is 20 each.
Logic"If the first two statements are true, is the final statement true? Some pitches use a DCF. Every DCF needs a discount rate. Some pitches need a discount rate. Yes, no or uncertain?"5
- 1Treat the statements as true, whatever you know about pitches.
- 2Follow the chain: the pitches that use a DCF are inside "every DCF".
- 3If the conclusion must follow for those pitches, answer yes.
- 4Answer uncertain only when the statements allow it to be false.
Tip: Written by Intervyo in a logic format. Not a Citadel item. Logic questions take longer than words, so do not let one take half a minute.
Example answer, written by Intervyo (not a real candidate)
Yes. The pitches that use a DCF need a discount rate, so at least some pitches need one.
FCAT: working capital"Revenue is $730m in 2027E and receivables are set at 45 days of revenue on a 365-day year. Receivables were $84m at the end of 2026A. What are 2027E receivables, and what does the change do to cash flow from operations?"13,16
- 1Turn days into a share of revenue: 45 / 365.
- 2Apply it to the same year's revenue.
- 3Take the change from the prior year-end balance.
- 4An increase in receivables uses cash, so it comes off cash flow from operations.
Tip: Written by Intervyo in the shape the FCAT accounts describe: a model built from given assumptions. Not a Citadel item. Get the sign right once, then copy the formula across the years.
Example answer, written by Intervyo (not a real candidate)
Receivables are $90m (730 x 45 / 365). They rise by $6m from $84m, so cash flow from operations falls by $6m.
FCAT: ratios"Net income in 2027E is $48m. Equity is $300m at the end of 2026A and $340m at the end of 2027E. The assumptions define return on equity on year-end equity. What is 2027E return on equity?"16
- 1Read the definition on the sheet before you reach for habit.
- 2Pick the denominator it names: year-end, not average.
- 3Divide and round as the answer box asks.
- 4Check it against the average-equity version, so you know which trap you avoided.
Tip: Written by Intervyo. Not a Citadel item. The FCAT has asked for a ratio on a point-in-time denominator where many people would use an average.
Example answer, written by Intervyo (not a real candidate)
14.1%: 48 / 340. On average equity of $320m it would be 15.0%, which is the wrong answer here.

How long to hear back after the online assessment
For those taken forward the next step comes quickly: in the full-time 2027 process business development interview invites came within days of the tests. For summer 2027 the recruiter call came first, then superdays in early January.13,12
Jan 2024 (summer 2024)
Software intern, New York
A HackerRank test within two weeks of applying: two questions, one medium and one hard, in 60 minutes. The process ended there.18
Dec 2025 (summer 2027)
Associate Program internship applicants
An information-session email listed the steps: a 15-minute online assessment, a Zoom interview with a recruiter, then a superday in early January.12
May 2026 (full-time 2027)
Associate Program applicant, referred
A business development call a week before applications opened, then the Wonderlic and the FCAT as soon as they applied, with one week to finish both.13
May to Jun 2026 (full-time 2027)
Associate Program applicants
One FCAT balance sheet did not fully balance at the 45-minute limit and still went through to the next round; another applicant took both tests late in a week and had a business development interview invite the next week.13
Jun 2026 (full-time 2027)
Associate Program applicant, New York
The FCAT and the Wonderlic, a 45-minute business development round, then three interviews with portfolio managers, over one to two months.14
Wonderlic gives candidates only a feedback report, through a link at the end of the test where the employer offers one, and no numerical cognitive score. Retakes are the employer's call.7,8
Best guessIf your summer 2028 internship invite names one 15-minute assessment, expect the Wonderlic: 12 minutes of questions plus its instructions. If a week passes after the tests with no word, keep your other processes moving.
What happens after the online assessment
Online application
A resume, education history and short questions on Citadel's own form for each route.1,2
Online tests (Wonderlic and FCAT; coding for software)You are here
This page. The Wonderlic, 50 questions in 12 minutes, for the Associate Program, with the FCAT modeling test (45 minutes) in the full-time 2027 process; a HackerRank coding test for software.5,13,14,18
First round (recruiter call; 45-minute video for software)
A Zoom interview with an Associate Program recruiter, or a 45-minute business development round; for software, a 45-minute video round on coding and your reasons for Citadel.12,14,4
Superday (three interviews)
For the Associate Program, a mixer with investors the evening before and three interviews with investment professionals; for software, usually three 45-minute interviews.12,4
Final round
A final round interview for the Associate Program; for software, a leadership interview with a senior engineer from an interested team, then a final review.12,4
Offer
An 11-week internship that opens with a one-week offsite; Associate Program interns rotate across investment teams.3,1
Wonderlic vs FCAT
Both came together in the full-time 2027 process, with one week for the pair, but they test different things. The Wonderlic is speed of reasoning; the FCAT is whether your model ties.
2028 summer analyst status
The Associate Program summer 2028 internship was taking applications by Oct 15, 2026, so its tests can come soon after you apply. Software roles for summer 2027 were posted by Jul 2026, so expect the summer 2028 postings, and the coding test after them, around June to August 2027.11
FAQ
What online tests does Citadel send?
It depends on the route. The Associate Program (investing) sends the Wonderlic cognitive test, and in the full-time 2027 process the FCAT modeling test with it. Software applicants get a HackerRank coding test.13,14,17,18
How long is the Citadel Wonderlic?
50 multiple-choice questions on one 12-minute clock, and Wonderlic does not expect you to finish. The summer 2027 internship email listed the online assessment as 15 minutes.5,6,15,12
What is the Citadel FCAT?
A modeling test: build a three-statement model in a web spreadsheet, on one clock, which ran 45 minutes in the full-time 2027 process. Expect a segment revenue build, a balance sheet that has to balance, ratio work and a simple valuation at the end.13,14,16
Can I use a calculator or Excel?
Not on the Wonderlic: no calculator, dictionary or other resources. The FCAT runs in its own web spreadsheet, not Excel; most Excel shortcuts do not work and not every Excel formula is available.6,7,13,16
How long do I have to finish the tests?
In the full-time 2027 process, one week to finish both the Wonderlic and the FCAT, with the links straight after applying or a few days later. Each test runs on its own clock once you start it, so book a quiet slot for each.13
Do summer interns take the FCAT?
Both dated FCAT accounts come from the full-time 2027 process, and the summer 2027 internship email listed one 15-minute online assessment. Expect the Wonderlic, and prepare for the FCAT in case it comes with it.13,14,12
Is the Citadel test the same as the Citadel Securities test?
No. Citadel Securities is a separate firm with its own page. The two firms share an engineering interview process, but the Wonderlic and the FCAT on this page are Citadel's.4,11,13
How do I prepare for the Citadel online tests?
For the Wonderlic, Wonderlic's own free timed practice questions, at about 14 seconds each. For the FCAT, timed three-statement builds from a blank sheet without shortcuts. For software, timed medium and hard coding problems in your chosen language.8,16,18
