Plan question practice for interviews.
Working through a question bank is a coverage problem: how many sessions the bank takes, and how long that is at your practice frequency. Sizing the session by questions rather than by minutes keeps each one bounded and finishable, which matters more for consistency than total volume. Six minutes per question allows for answering aloud and then critiquing the answer, which is where the improvement actually comes from.
Question bank coverage
Sessions = ceiling(bank size / questions per session); weeks = sessions / sessions per week; session length = questions per session x minutes each
Forty to eighty for a behavioural interview covers the realistic space, since most questions are variations on a dozen underlying themes. Technical banks are necessarily larger because the problems are genuinely distinct.
No. A second pass focused only on the questions that went badly is worth more than the whole first pass, because spaced repetition on weak answers is where measurable improvement happens.
Because the failure mode in interviews is verbal — rambling, losing the thread, or burying the outcome. Rehearsing silently does not surface those problems, which is why the per-question allowance includes speaking time.
