NYC Sanitation Worker common mistakes

NYC Sanitation Worker · Understand the traps and how to avoid them.

Mistake 1

Treating 'safety first' as the answer to every scenario question, even when the question asks about efficiency, customer service, or procedure order.

Candidates hear that the job is safety-critical and over-apply the safety lens, choosing the most cautious option even when the scenario is about handling a resident complaint or completing a route on time.

What to do instead

Read the question stem for its actual ask before reading options. If the stem mentions a resident, a route, or a form, the best answer usually follows procedure or service standards rather than simply being the most cautious choice. Practice sorting a set of questions by what each is really asking.

Mistake 2

Answering reading-comprehension items from memory of the passage topic instead of locating the specific sentence that supports the choice.

The passages are short and familiar-sounding (notices, memos, work orders), so candidates skim and pick the option that 'sounds right' rather than verifying it against the text.

What to do instead

For every comprehension item, point to the line in the passage that proves the answer. If no single line supports an option, eliminate it. Practice with short notices and write the supporting phrase next to your chosen answer.

Mistake 3

Rushing the math and measurement items and making unit or place-value errors, such as mixing feet and inches or misplacing a decimal.

Arithmetic on the written exam is basic but presented in work contexts (tonnage, distances, container counts), and candidates who are anxious about time skip writing out the units.

What to do instead

Write the unit next to every number before calculating and convert to a common unit first. Do a rough estimate before computing so an off-by-ten answer is obvious. Drill 10 mixed unit-conversion problems daily until the conversions are automatic.

Mistake 4

Choosing the first plausible answer and moving on without reading all four options.

Time pressure and the desire to bank easy points leads to early commitment; distractors are written to look correct at a glance.

What to do instead

Force a habit: read all four options, then eliminate at least one before selecting. On flagged items, come back and re-read the stem with the chosen option inserted to confirm it answers the question asked.

Mistake 5

Misreading negatively worded stems such as 'Which of the following is NOT...' and selecting the true statement.

Under time pressure the eye skips the small capitalised 'NOT', and the brain answers the more familiar positive version of the question.

What to do instead

Circle or underline 'NOT', 'EXCEPT', and 'LEAST' whenever they appear before reading the options. Restate the stem in your own words as a positive question, then pick the option that does not fit.

Mistake 6

Skipping or guessing on the situational-judgment items about interpersonal conflict, supervision, or resident interaction, treating them as unanswerable opinion questions.

These items have no formula, so candidates assume any answer is defensible and pick at random instead of applying a consistent standard of professional conduct.

What to do instead

Adopt a fixed decision rule: follow policy, address the issue directly and respectfully, escalate through the chain of command when appropriate, and protect public safety and property. Test each option against that rule and eliminate options that avoid the problem, blame others, or bypass procedure.

Mistake 7

Leaving answers blank on items that are uncertain, believing a blank is safer than a wrong guess.

Candidates carry over a habit from exams with guessing penalties or from fear of looking foolish, even when the exam scores only correct answers.

What to do instead

Confirm the scoring rule for your sitting. If there is no penalty for wrong answers, never leave a blank: eliminate what you can and guess from the remainder. Budget the last five minutes for filling every unanswered item.

Mistake 8

Spending too long on one hard item and running out of time for the final third of the section.

Pride and anxiety combine so that candidates refuse to abandon a difficult question, losing points on easier items later in the section.

What to do instead

Set a per-item time cap based on the section length and number of questions. If an item exceeds the cap, mark it, pick a provisional answer, and move on. Practice full-length timed sets so the pacing becomes routine.

Mistake 9

Ignoring the instructions at the top of each section and applying the wrong format, such as writing a full sentence where a single letter or number is required, or missing that a section has a different time limit.

Candidates jump straight to question one and assume every section works the same way.

What to do instead

Read the section directions in full before answering, noting the response format and time limit. On practice tests, deliberately vary formats so you get used to switching.

Mistake 10

Failing to review basic map, direction, and spatial-relationship items, assuming street-smart knowledge will carry them.

Direction and map-reading items feel trivial, so candidates skip practice, then confuse left and right turns or misread a compass when the item is phrased with a rotation or a facing direction.

What to do instead

Practice with simple grid maps: draw the route, mark north, and physically turn the page to match the direction you are facing. Do ten direction-and-turns items per session until the method is reliable.
