Top 4 Aptitude tests Interview Questions
Browse 4 real-world technical and behavioral interview questions about Aptitude tests. Review scenarios, edge cases, and architectural best practices.
Numerical reasoning tests give you percentages, ratios and data tables against the clock. Which shortcuts keep you fast and still accurate?
In numerical reasoning tests, use multipliers for percentages so successive changes combine by multiplying, separate percentage change from percentage points, scale ratios to a common term, and estimate before calculating so the rough figure rules out wrong options and checks your exact one.
Permutations, combinations and probability in aptitude tests: how do you count without double counting?
Decide first whether order matters: permutations if it does, combinations if it does not. Divide out repeated items, and for "at least one" count the complement and subtract. Picking one item first and then the rest freely double counts, because each outcome is reached several ways.
Syllogisms and seating arrangements: how do you avoid the answer that is designed to look right?
Solve syllogisms by drawing the weakest diagram the statements allow and accepting a conclusion only if it holds in every diagram, remembering that "some" means at least one. Solve a seating arrangement by placing fixed clues first, branching on the rest and eliminating, never stopping at the first layout that fits.
Time, speed and distance problems and work-rate problems keep eating your aptitude-test minutes. Is there one method that handles most of them?
Yes. Time, speed and distance and work-rate problems are the same equation, amount = rate × time. Rates add when things work together or move towards each other and subtract when they oppose; for work, set the job to the LCM of the times so each rate is a whole number of units.
