Time Commitment: What to Expect

Now, let’s get to the core question: how much time will you need to finish the Optiver Junior FPGA Engineer online assessment? The answer isn’t a simple number, as it depends on several factors, including your current skill level, familiarity with the topics, and your test-taking strategy. However, we can provide a general idea to help you plan.

Factors Influencing Time

  • Your Experience Level: If you’re fresh out of university with a degree in electrical engineering or computer engineering, you might need to dedicate more time to preparation compared to someone with a few years of industry experience. Recent graduates may have the theoretical knowledge but might lack practical experience, while experienced engineers might need to refresh their memory on certain fundamentals.
  • Your Familiarity with FPGA Concepts: If you've worked extensively with FPGAs and HDLs, you’ll likely be able to complete the assessment faster. Those who have completed multiple FPGA projects or have hands-on experience with different FPGA development tools will have an advantage. However, if you're relatively new to this field, be prepared to spend more time studying and practicing.
  • The Assessment Format: The format of the assessment also plays a role. Is it multiple-choice, coding-based, or a combination? Coding-based questions might take longer as they require you to write and debug code. Multiple-choice questions might be quicker to answer, but they can still be tricky if they require in-depth knowledge.
  • Your Test-Taking Strategy: How you approach the test can also influence the time you take. Are you methodical, working through each question carefully, or do you prefer to quickly answer the easy questions first and then come back to the more challenging ones? A good strategy can help you manage your time effectively and maximize your score.

Estimating Preparation Time

For most candidates, we recommend dedicating at least 20-40 hours of preparation time. This might seem like a lot, but it’s better to over-prepare than to feel rushed during the assessment. This time should be spread out over several weeks to allow for better retention and to avoid burnout.

  • Beginner: If you're relatively new to FPGA concepts, you might need closer to 40 hours or more. This time should be spent learning the fundamentals, practicing with HDLs, and working through example problems.
  • Intermediate: If you have some experience but feel you need a refresher, 20-30 hours might suffice. Focus on reviewing key concepts and practicing with more complex problems.
  • Experienced: Even experienced engineers should dedicate some time to preparation, perhaps 10-20 hours, to ensure they are familiar with the specific topics and format of the assessment.

Time During the Assessment

As for the actual assessment time, this can vary. Optiver usually provides a specific time limit for the assessment, which could range from 1 to 3 hours. Make sure you know the exact duration beforehand so you can pace yourself accordingly. During the assessment, time management is crucial. Allocate a specific amount of time for each question or section and stick to it. If you’re stuck on a question, don’t spend too much time on it; move on and come back to it later if you have time.
