If there are three other apprentices, she may be able to make friends with them and socialise with them, it depends if they are all in different departments, I’d assume they are ie one in property, one in aviation, one in litigation etc.and how often they are brought together, how much she likes them or they her.
The issue she will have is she will be substantially younger than the rest of the staff, she maybe will be closer in age to the junior paralegals, but they will have completed their degrees as a min and possibly also their lpcs over two years after their degrees,, so a very different level of Maturity and experience.
The fee earners, ie the solicitors, associates and partners clearly much older and likely not willing to socialise past work events,.
Those on a training contract (trainee solicitors ) will also have completed their degrees and done their lpcs, over one or two years, so again a different level of maturity, they also only do six months in any one seat (dept basically ) as they complete their qualifying period over the two years, so wouldn’t be in her dept for long anyway .
So I’d say it’s possible she finds friends, but due to her age, and experience, she may find she doesn’t have much in common with, others.
The other apprentices also could be younger than her, Ie straight out of school.
I would say this would not be the guaranteed way to make friends. To put it into context these guys are working 14 hour days min, the pace is brutal, the atmosphere tense and busy, and as much as she may find personal friends and a social life , she shouldn’t be looking at it for that purpose as there is a significant chance it might not happen.
However nor should she go to uni just for the social circle. She needs to pick based on the best career choice.
She may be lonely if she’s not working currently or at uni. A job may change that when she’s busy,
