Numerical Reasoning Gym
The online test rejects more applicants than any interviewer, and it is the one stage you can straightforwardly train: read a small table, pick the right base, do clean arithmetic under a clock. This drill rebuilds that exam, with the tempting wrong answers included on purpose.
Ten questions, seventy-five seconds each: percentage changes, shares of total, ratios, currency conversions and per-head figures, read off small tables the way the real tests present them. The wrong options are the wrong turns real candidates take.
Fresh numbers every run. When the clock reaches zero the question counts as wrong and the next one loads; there is no going back. Paper and a pen are allowed in most real tests, so use them here too.
