What this tool does
Formula quiz is the multiple-choice check on the Engineering hub. Ohm, kilometres, freezing point, and F = ma. There are 4 items. Each item has one keyed option. The page is there so you can rehearse the distinction before an interview, not so the site can rank you against other people. Item 1 asks “Ohm's law, as used in the converter, is”. The option this quiz marks correct is “V = I × R”. Voltage equals current times resistance when you supply two of the three. The other choices are V = I / R; P = V / I always without resistance; F = ma. Item 2 asks “1 kilometre equals”. The option this quiz marks correct is “1,000 metres”. The unit converter uses 1 km = 1,000 m. The other choices are 100 metres; 10 metres; 1,000 millimetres. Item 3 asks “Water freezes at”. The option this quiz marks correct is “0 °C”. 0 °C is 32 °F and 273.15 K in the converter. The other choices are 100 °C; 32 °C; 273 °C. Item 4 asks “Force in Newton's second law is”. The option this quiz marks correct is “Mass times acceleration”. F = ma. The quiz does not replace a design calculation. The other choices are Mass divided by acceleration; Velocity times time only; Pressure times volume.
How to use it
Read the prompt, pick one option, and submit the set. You do not need an account to try it. Three correct answers out of four score 75, because the score is correct divided by the number of items, times 100, rounded to the nearest whole number. A wrong pick still leaves the explanation on the item, which is the useful part. The score is not a grade from an employer and it is not sent anywhere by itself. If you want it kept, sign in as a candidate and save the attempt. The quiz does not use a model, so it runs the same way when no AI key is configured.
Worked example
Work the first item on its own before you look at the key. It asks “Ohm's law, as used in the converter, is”. If you choose “V = I × R”, that item is marked correct because Voltage equals current times resistance when you supply two of the three. Then do the rest without changing an earlier answer to chase a round number. A perfect set scores 100. One miss on a four-item quiz scores 75. Zero correct scores 0. None of those numbers is a percentile. The jobs link on this page searches HiringBuddy for published roles matching “engineer”. An empty list means nothing published matched. It is not a comment on the wider market. A signed-in candidate can save the attempt on their profile. Saving is not an application, and it does not show the attempt to an employer. Employers see people who apply to their own jobs.
Questions
- How many questions are on the Formula quiz?
- This page has 4 items. The score uses that count as the denominator.
- Does a high score go to an employer?
- No. Saving an attempt stores it on your candidate profile. An employer sees applicants to their own jobs, not this quiz.
- What does the score actually measure?
- It measures how many keyed options you matched. It does not measure speed, and it does not compare you with anyone else.
- Can I retake it?
- Yes. The items stay the same, so a retake checks whether the explanation stuck. It is still practice.
