Welcome to the forum! Imposter syndrome is completely normal - but I can assure you that the firms recruiting graduates do not expect you to have done an abundance of work experience (my TC offer following a VS was the first corporate law work experience I had ever done, I also had only mini pupillages) - but remember that there's so many virtual internships through Forage that you can do which will help your applications. It is also okay to make mistakes - the application process is daunting and video interviews are very difficult. Keep practising and you will only get better!
