US pre-employment tests come in three kinds, and only one rewards drilling

Retail and service employers mostly use work-style questionnaires and job simulations. Walmart describes an assessment custom-built from its own job analysis, CVS Health screens many high-volume roles with a Virtual Job Tryout, and Starbucks says an application that includes its Applicant Insights assessment is not complete until you finish it.

Telecoms employers lean on knowledge and aptitude batteries. AT&T posts its own study guides for tests such as the BAT and OP-TAB, and Verizon describes a Minicourse that teaches material during the test. Technology employers and coding schools use the CCAT, a pure speed-and-reasoning test.

Crossover sets the CCAT twice, the second time under live proctoring. BloomTech publishes a cut-off of 23 out of 50. Hack Reactor and Tech Elevator use it for admission. Fifty questions in fifteen minutes punishes hesitation, so timed practice moves scores more here than anywhere else in this guide.

Take our free CCAT practice test once, note which of verbal, maths and logic cost you most, and drill that before your real sitting.

Job tryouts show you a day in the job, such as a customer complaint or a stock problem, and ask what you would do. There is no answer key to learn, and Walmart says as much. What helps is reading the employer's stated values, answering as a reliable, safety-minded colleague would, and staying consistent, because similar questions often come back in different words.

Home Depot describes 53 text-based questions with 96 hours to finish once started. Wells Fargo teller applicants report a tryout of about 99 questions in five sections. Do them in one calm sitting, on a laptop, with your availability decided in advance.

Not every application includes an assessment. UPS says for most jobs the last step is choosing a start date, and Publix says many store roles go straight to interview. Target says only some applications include a short skills check. If your application has no test, put the time into availability and interview answers instead.

Where a role adds maths, it is usually store maths: change, percentages and simple measurements. Pharmacy technician roles at CVS and Walgreens are different, because dosage and label reading matter there.

Many US employers lock you out for a period after a failed assessment, often six months to a year, and some, like Delta, ask you to complete the assessment without interruption. Crossover allows one attempt per email every six months. Treat the first sitting as the one that counts.
