• The Optiver hiring assessment is typically an online screening test designed to measure reasoning, accuracy, and speed.
• It commonly includes logic/pattern reasoning, numerical reasoning, and instruction-following tasks, sometimes with situational judgment.
• Most people struggle because of time pressure, tricky wording, fatigue, and second-guessing.
• Preparation helps by building pacing, sharpening patterns you’ll see repeatedly, and reducing careless errors.
• In addition to this test Employers often test core skills such as Cognitive Skills, Attention to Details, and Problem Solving to ensure candidates can effectively analyze data, maintain accuracy, and address complex challenges. Additionally, skills like Customer Service, Leadership, Communication, and Situational Judgement are critical for fostering positive interactions, guiding teams, conveying ideas clearly, and making sound decisions in varied scenarios.

The Optiver assessment is a pre-employment test used to evaluate how candidates process information and solve problems quickly. It is typically built to measure core skills that matter in fast-paced roles, such as reasoning accuracy, mental math, and consistent decision-making. Many versions include logic or pattern questions that reward noticing rules and eliminating wrong options efficiently. Numerical sections often test speed with arithmetic, estimation, and interpreting simple data under time limits. Some assessments also include reading or instruction-following items that punish skipping details or assuming what the question says. Attention to detail can show up through small traps like reversed conditions, “except” wording, or multi-step instructions. Situational judgment questions may appear to evaluate how you prioritize, communicate, and stay calm in ambiguous scenarios. People often struggle because the timing feels tighter than expected, which leads to rushed errors. Others struggle because they overthink, change answers late, or lose time on one hard question. Fatigue is another common issue, especially if the assessment is multi-part and you don’t pace yourself. Good performance usually looks like steady accuracy, quick elimination strategies, and a consistent rhythm rather than perfect answers on every item. The goal is to be fast and reliable while staying focused through the full session.

How It’s Used in the Hiring Process

In many hiring processes, the Optiver assessment appears shortly after you apply, sometimes within days of submitting your application. In other cases, it is sent after an initial resume screen to confirm baseline fit before interviews. Employers use assessments like this because they create a standardized way to compare candidates across schools and backgrounds. Instead of relying only on resumes, they can evaluate how you perform on the same types of tasks under the same constraints. Results are typically used as a screening signal, not the only decision point, but it can strongly affect whether you get interview invites. Companies like this approach because it is efficient, consistent, and easier to scale when they receive many applications. It can also highlight candidates who perform well under pressure even if their background is less traditional. If you do well, the next step is often a recruiter call, technical interview, or a set of deeper interviews depending on the role. Some candidates may be asked to complete additional rounds, such as role-specific tasks, problem-solving interviews, or team-fit conversations. If you don’t pass, you may be screened out early even if your resume is strong. That’s why the smartest approach is to treat the assessment like a skill test you can train for, not a one-time mystery event. The more prepared you are, the less you rely on luck and the more you control your outcome.

Sample Questions and Recommended Answers (Practice-Style)

1) Logic/Pattern Reasoning

Question: Find the next number in the sequence: 2, 6, 12, 20, 30, ?
Recommended Answer: 42
Explanation: The differences are +4, +6, +8, +10, so the next difference is +12. Add 12 to 30 to get 42. This tests whether you spot a rule based on changing gaps.

2) Logic/Pattern Reasoning

Question: A rule transforms a number as follows:

• Input 3 → Output 10

• Input 5 → Output 26

• Input 7 → Output 50
  What is the output for input 9?
  Recommended Answer: 82
  Explanation: The pattern is output = (input²) + 1. For 3: 9+1=10, for 5: 25+1=26, for 7: 49+1=50. For 9: 81+1=82.

3) Logic/Pattern Reasoning

Question: In a code, “TAR” means “red fast,” “LAM” means “fast car,” and “NOK” means “red light.” What word most likely means “red”?
Recommended Answer: TAR or NOK share “red,” so “red” = the common code element between TAR and NOK (not given explicitly), meaning you’d identify the shared syllable if present.
Explanation: This is a logic mapping question. You look for overlap: TAR and NOK both include “red,” so the shared code part would represent “red.” If no shared part exists, the set is inconsistent by design—your best move is to avoid guessing and pick the option that reflects “shared element = shared meaning.”

4) Numerical Reasoning

Question: A trader buys 80 shares at $25 and sells them at $28. What is the profit? (Ignore fees.)
Recommended Answer: $240
Quick Working: Profit per share = 28 − 25 = 3; total profit = 80 × 3 = 240.
Explanation: This checks basic arithmetic under speed. The trap is mixing up total sale value versus profit.

5) Numerical Reasoning

Question: You have 12 minutes to answer 24 questions. If you spend 40 seconds per question, how many questions can you complete?
Recommended Answer: 18 questions
Quick Working: 12 minutes = 720 seconds; 720 ÷ 40 = 18.
Explanation: This tests time budgeting. It also hints at pacing strategy: you can’t afford long stalls on tough items.

6) Numerical Reasoning

Question: A value increases by 15% and then decreases by 15%. Is it back to the original value? If not, what is the net change?
Recommended Answer: It is not back to the original; net change is −2.25%.
Quick Working: Start 100 → up 15% = 115 → down 15% of 115 = 17.25 → 115 − 17.25 = 97.75.
Explanation: Percent changes apply to different bases. This common trap checks whether you understand compounding.

7) Reading/Instruction-Following

Question: Read carefully: Choose the option that is NOT a multiple of 6.
A) 18 B) 24 C) 30 D) 35
Recommended Answer: D) 35
Explanation: Multiples of 6 are divisible by 2 and 3. 18, 24, and 30 fit; 35 does not. The main skill is not missing the word “NOT.”

8) Reading/Instruction-Following

Question: Instruction: Select the statement that is logically supported.
Statement: “All analysts in Team A use Tool X. Some Tool X users work remotely.”
Options:
A) All Team A analysts work remotely
B) Some Team A analysts might work remotely
C) No Team A analysts work remotely
D) All remote workers use Tool X
Recommended Answer: B) Some Team A analysts might work remotely
Explanation: We know Team A analysts are Tool X users, and some Tool X users are remote. That does not guarantee Team A is remote, but it allows the possibility. This rewards careful logic, not assumptions.

9) Situational Judgment

Question: You are in a timed assessment and hit a question you can’t solve after 45 seconds. What’s the best next move?
Recommended Answer: Skip it, mark it if possible, and keep your pacing.
Explanation: In most timed tests, one hard item can cost multiple easier points. A disciplined skip strategy protects your score and reduces panic. Come back only if you have time at the end.

10) Situational Judgment

Question: You notice you keep making small mistakes because you rush. What adjustment is most effective during the test?
Recommended Answer: Slow slightly on the setup (reading and identifying what’s asked), then answer quickly once clear.
Explanation: Many errors come from misreading, not math or logic. Taking an extra second to confirm the target reduces avoidable mistakes while still keeping pace.

How to Prepare Efficiently (Using JobTestPrep Materials)

A realistic way to prepare is to train two things in parallel: accuracy and speed. Start by learning the common question types and the patterns that show up repeatedly, then add time pressure gradually. In the first sessions, focus on getting questions right and understanding why the correct answer works. Once you can solve them calmly, move to timed sets to force faster decisions. This is where JobTestPrep-style materials can help because they let you practice in formats that feel similar to real screening tests. Timed practice sets build your ability to keep a steady rhythm without panicking. Topic drills help you isolate weak areas, such as number speed, pattern rules, or “trick wording” reading items. Full practice tests are important because they build stamina and teach you how performance changes when you’re tired. Detailed explanations matter because they show repeatable methods, not just answers, so you stop repeating the same mistake. A structured study path also prevents wasted time hopping between random problems without improving. Treat every mistake like data: identify the cause (misread, slow setup, wrong rule, arithmetic slip) and adjust. Don’t assume you need hours per day; consistency and targeted practice often beat long, unfocused sessions. Also avoid overtraining right before the test—burnout can reduce accuracy. Finally, remember that prep materials are practice tools, not “official” sources, and no resource can guarantee a specific outcome. What you can control is your process: practice under time, review errors, and build repeatable strategies.

3-Day Crash Plan

• Day 1: Take one diagnostic timed mini-test; list your top 3 weakness areas and top 3 error types.

• Day 1: Do targeted drills for the biggest weakness (e.g., number speed or patterns) and review every mistake.

• Day 2: Complete two timed sets (mixed questions), focusing on pacing and quick elimination.

• Day 2: Build a personal “trap list” (NOT/EXCEPT wording, unit errors, rushed arithmetic, overthinking).

• Day 3: Take a full timed practice test; simulate real conditions (quiet, no interruptions).

• Day 3: Review mistakes, then do a short final drill session on your weakest area only.

7-Day Plan

• Day 1: Diagnostic timed set + error log (what happened and why).

• Day 2: Logic/pattern drills + one timed mixed set.

• Day 3: Numerical speed drills (percent, ratios, time, estimation) + review.

• Day 4: Reading/instruction questions + timing strategy practice (skip/return rules).

• Day 5: Full practice test under realistic conditions + deep review.

• Day 6: Targeted drills based on the review + one timed mixed set.

• Day 7: Light practice only (short timed set), then focus on rest and readiness.

14-Day Plan

• Week 1 (Days 1–3): Learn formats + do untimed practice to lock in methods, then add light timing.

• Week 1 (Days 4–5): Two focused days: one for logic/pattern, one for numerical reasoning, with error review.

• Week 1 (Days 6–7): Full practice test + review; then a shorter mixed set to apply fixes.

• Week 2 (Days 8–9): Timed sets only, aiming for consistent pacing and fewer “silly” errors.

• Week 2 (Days 10–11): Two more focused days on weakest sections, with strict time limits.

• Week 2 (Day 12): Full practice test under realistic conditions + review.

• Week 2 (Day 13): Light mixed set + finalize your approach (skip rules, time checkpoints).

• Week 2 (Day 14): Rest-focused day with only a short warm-up drill if you feel anxious.

Day-Before Checklist

• Do a short 15–25 minute warm-up set (not a full test).

• Review your error log and “trap list” one last time.

• Decide your skip strategy (when to move on, when to return).

• Prepare a quiet space, stable internet, and a charged laptop.

• Sleep plan: set a realistic bedtime and avoid late caffeine.

• Eat normally; avoid experimenting with new foods or supplements.

• Set out scratch paper, pen, and water if allowed.

Test-Day Checklist

• Start with a quick mental warm-up (a few easy problems to feel sharp).

• Read every question stem carefully, especially NOT/EXCEPT wording.

• Use checkpoints (example: after 25% of time, aim for ~25% of questions).

• If stuck, skip early and protect easier points.

• Avoid changing answers unless you can name the exact mistake you made.

• Keep breathing steady; reset after any error and move forward.

• Maintain posture and focus—fatigue drives sloppy reading.

• Finish strong: use final minutes to return to flagged questions only.

Key Takeaways

• Train for timing and pacing, not just correctness.

• Use error logs to eliminate repeated mistake patterns.

• Practice with timed sets and full-length tests to build stamina.

• Enter the assessment with a clear skip strategy and calm focus.

FAQs

How long is it?
It varies by role and version, and it’s often split into multiple timed sections. Expect tight time limits that reward quick decisions more than perfect solutions.

Is it proctored?
Some versions may be monitored, while others are unproctored but still time-controlled. You should assume your session may include integrity checks and follow the instructions you receive.

Can I retake it?
Retake policies vary by employer and timing, and many companies limit how often you can attempt the same stage. Treat your first attempt seriously and prepare as if it’s your main shot.

What score do I need?
Companies typically don’t publish exact cutoffs, and thresholds can depend on role and applicant volume. The practical goal is to maximize accuracy while maintaining pace across all sections.

What if I’m not strong at math or logic?
You can still improve quickly with targeted drills and repetition, especially on common patterns like percent change, ratios, and sequence rules. Focus on method and speed fundamentals rather than trying to learn advanced math.

How do I avoid running out of time?
Use a strict skip rule, avoid long stalls, and keep an internal pace check as you go. Most candidates lose time by overthinking one item instead of collecting points across easier questions.

Should I guess if I’m unsure?
That depends on the test rules, but in many timed assessments, an educated guess can be better than leaving blanks if there’s no penalty. The safest approach is to eliminate wrong options quickly, then choose and move on.

How much preparation is “enough”?
If you can complete timed practice sets with steady accuracy and you’re no longer surprised by question formats, you’re in a good place. Most gains come from correcting repeat errors and improving pacing, not from endless hours of practice.
