[Grammar] '... education promises that vital first hire,...'

[Bebop7]

Here is the whole context:
'Although a vocational education promises that vital first hire, those with specialised training tend to withdraw from the labour force...'

I think the underlined part as a kind of noun phrase; that is (that vital first/ hire(noun)). My question is why 'that' is used instead of 'the' and what the part does exactly mean.

"That" (not "the") is used to refer to something/someone while attributing something special to it/them. Look at explanation #3 of "that" as a determiner in the link below.

I am sorry if I might sound impolite to you. Next time, I will not forget to use the basic request sentence.

I'm still confused. Can you give me more explanation? I'm wondering how "that" as a determiner can be applied to the original sentence.

 

[teechar]

A vocational education helps young people to get that special, all-important, confidence-building first job.
Does that help?

Yes, that does help. Thank you.
one more follow-up question. I think that the determiner 'that' is more close to the explanation #4 in the OED - Referring to a specific person or thing assumed as understood or familiar to the person being addressed. Because the author assumes that first job is special and all-important to both him(her) and us(readers). I'd like to hear your thoughts.

I think it's closer to #3, but I can accept your reasoning.
