Honestly, what made the biggest difference for me was - mindset. After failing to convert my first vac scheme into a training contract and then failing to get any vac schemes for two years, I was devastated. I spent two years going through hundreds of applications made by other students trying to identify a formula for how to write successful applications without any avail. In all honesty, I equated my value and self-esteem with a training contract and vac scheme, thus allowing every rejection to bring me down just a little bit more. This was definitely the most toxic thing I have ever done to myself because instead of emphasising my own characteristics and skills and interests in applications, I was now in a mindset where I was constantly comparing myself to other applicants and feeling pretty low about myself. Mind you, this problem was a lot harder to deal with because I am also an international student and in my Asian country there is an incredible amount of pressure to be successful, especially if you study abroad, and failing to convert a degree into a job abroad is usually quite shameful in the society I come from. All of this translated into the quality of applications I was sending out, because they were now looking increasingly replicated and generic and did not nearly cover my interests + skills adequately.
So last year, after I graduated, I genuinely asked myself - is this career still something I want and something I am equipped for, or is it peer-pressure from being in law school and only being considered successful if you have an 'incoming trainee solicitor' tag on linkedin? I have always been deeply interested in law and enjoyed all my exposure to law firms, so I knew this was definitely the career I wanted and then this became the starting point for me to recalibrate my mindset.
Over the last year then, I only made applications to firms that genuinely interested me, even if they were slightly smaller, and avoided making applications just for their prestige or reputation. I focussed on myself and my interests, attending virtual law fairs and speaking to solicitors about the work they did to understand what practice area focus should I maintain. A tip here (and this might be slightly controversial) is that I did not let any peers proof-read my applications - I did this because for me personally, this exercise was a gateway to doubting myself and letting other people dictate what I should convey about myself rather than choosing myself. I also focussed on shedding away some of my writing flourish and chose instead to write in a direct and mature manner - always answering the question and linking the skill/experience back to the firm without giving excessive details. Finally, and this was something I was only able to do after graduating, was making early applications. Most assessment centres I secured this year involved me sending out the application a day or two after the firm's window opened, so I will really really recommend if you can to send out the application super early!
In the end, if I had to summarise and talk about the single most effective tip to getting a tc - it is resilience. As long as you keep dusting yourself off, recalibrating, re-applying and reconsidering your career goals, you will get that TC. Regardless of the external pressure associated with this career, only you determine your self-worth and I promise that if you just keep making those applications - something incredible will come out of it
