Yes, but most of those are the same as spending the whole time doing nothing but making applications. Also if they ask 'tell me about yourself' and its February, and you finished with 'i graduated 8 months ago' there will certainly be warning sirens in the mind of the interviewer as to what you've been doing, and they will likely ask you what you've done since then or ask for a more recent example to a question. Even doing something like working in a pub 'building my interpersonal skills' etc. would be expected if nothing else. Open days and virtual events, whilst demonstrating an interest in the law, don't really show the same pro-activeness that someone doing the same whilst working part time/full time would show.There is no reason for you to mention that you haven’t worked post-grad when they ask you “why law” or “tell me about yourself” imo. Infact, CV Blind interviews will work in your favour especially if you have gaps. Although yes, no activity post-grad for a year will probably be frowned upon hence why I suggested open days and virtual events during the milkround. I think firms are very much aware that the process is competitive and finding a job right after uni is not possible for everyone. Baring in mind for instance international students may not have access to jobs like we do, those that move back to remote (country/village) areas after uni, or personal circumstances like disability etc. Some people will also have their own entrepreneurial pursuits or extra curriculars after uni which could count towards work experience.
At the end of the day, you could do nothing but apply and maybe do some virtual presentations if you really want- but top law firms get thousands of applications, and you will be disadvantaged if you aren't showing at least some effort beyond the bare minimum.
