By chambers of the arrival of pupils.
when did this he come a thing? I guess it is a huge investment and competition (by chambers and students respectively). But it is a big cultural shift.
Way back when, as a pupil you were not on the marketing map. Not until you had made a mark and the set had decided to take you on, and even then you needed first to deliver on the show of trust in you and on your potential, by handling instructions well, impressing instructing solicitors and silks, developing the grains of a reputation. Getting lucky and building on that. Took some time. In many ways invisibility was a relief- no undue pressure while you found your pace. I feel for these pupils and the weight of expectation.
