Hi
@commercialhoe-yer, it is great to hear from you - you sound like a very thoughtful person and I am sure that you absolutely have what it takes to get a TC! I definitely know shy/introverted people who have received TC offers and they are often the smartest and kindest of the bunch! Remember that the people interviewing you may have lacked confidence themselves at one point; that could subconsciously warm them to someone more like themselves. There is definitely an element of the luck of the draw when it comes to who your interviewers are.
I had the same idea in mind as you when I attended interviews and vac schemes. I remember identifying a whole range of charming, well-presented individuals at the beginning of the day or week, whom I was certain would be a shoo-in! This did not come from a place of annoyance, as they were often lovely people who seemed very knowledgeable - it simply made me feel like I was competing for one of the 'remaining' spots 🤣
Often I was completely surprised when I found out who ended up getting the offers - not because I think that those who did receive an offer didn't deserve it, but because I had formulated an image of the perfect lawyer in my mind and the individuals who fit this description did not always end up getting offers.
The point here is that everyone on your interview (including you) will be exceptionally well qualified. Ultimately, it will come down to how well prepared you are for your interview and whether you are a good fit with the firm. Many practice areas have significantly less client contact than others and being a 'people' person does not necessarily mean being able to work the room; it just means that you are kind, respectful and reliable to those who are entrusting you with their work. As long as you show up to your interviews with a lot of knowledge about the firm and genuine interest in its work, then you will have put yourself in the best position possible to get a TC. I really would not try to be someone who you are not.
Nevertheless, it is definitely possible to prepare answers to the 'casual' questions so that you do not feel caught out in your interview. You can find a list of some such questions which may arise
here.
There are also some ways to work on building rapport, which I have written about
here. Do let me know if this is all helpful and whether you have any other questions about it
