well my school encouraged us to do work experience in jobs that you're interested in and none of my friends were interested in what I wanted to do (architecture stuff) so I did mine by myself and boi was it boringgg. but at the same time quite a few people in my year did work experience at boots and they were all together in a group so its up to you really.
for my work experience I went to this engineering/architecture company and basically sat at a computer for 5 days using design software to connect pipes and ventilation and stuff (yes i know it sounds absolutely riVeTinG i just love pipes sO mUCH) i'm kinda awkward and shy so I didn't talk to anyone that much so I was basically working by myself the whole time
