In no different way than they should have been if the vacation schemes took place.
Some firms whose vacation scheme recruitment process replicates the TC process may make direct offers. But even then it would only be to candidates they were exceptionally confident would meet the benchmark.
When you assess vacation scheme candidates you ultimately are looking for different things (you can be a bit more open minded/take more risks with VS candidates).
You can’t do that with TCs - the level of investment is far too high to take a punt on someone.
Some firms will just recruit later though - I wouldn’t expect all firms to make VS candidate direct TC offers instead. For those firms that do choose this route, it will only be a proportion of training contracts they offer anyway.
