Each generally has an hour slot, but it's not unusual to end earlier. The folks that we have at the interview stage are generally very interested in proceeding. (It may be helpful to know that we are very (very) oversubscribed from a hiring perspective; I know that this is not usually (or often) the case. Though, if I may add: we are oversubscribed in part because we have built an incredible team through a thoughtful process.) And, as I've said to others: we're not necessarily a fit for everyone, so we're always understanding if our process is too much or otherwise represents a poor fit.
