Because these two do not have corporate-grade like HR departments that are too busy showing the rest of the company how invaluable their work is. Keeping busy makes you busy.
Instead, small operators are looking for pilots who arrive on time as much as practicable with a reusable aeroplane and without spreading dangerous habits among the pilot pool. For this, you need a SIM session and an assessor pilot who's seen a bit of the dark side - and done. Makes you wonder what else is there actually to the job that other companies are so keen to discover. The whole of DLR could not prevent the GW tragedy.
BTW: a fresh rumour is going around, about WZZ calling the people who turned them down the last autumn and in spring time (say again: pilots refused to join the pink T&Cs), but now offering the original salary packages on a flexible contract. After the second finger is shown some threats are issued (blacklist) but ulitmately another call follows a couple of days later with the contract attached for the standard duty pattern on pre-covid terms.
This smells a bit like normality is coming, at last.
