Hi guys, I was asked in a DM about how to convert a VS to TC and this was what replied. Thought I would share - it is all my personal opinion/experience (at US firms btw).
Congratulations on securing the VS! I think the VS to TC conversion comes down to several elements.
First, your attitude! This is probably the most important thing within the process. They are looking for individuals who mesh well with others, are nice to work with. Basically can they stomach you for 10-12 hours a day. Your attitude has to be positive and respectful (especially to those more senior than you) and watch out with negative comments. This will be flagged in your feedback. Don't shit on the work given to you, just smile and do it! Its only 2 weeks and you won't be of much use so the work will probably be monotonous. Same goes for the events set up by GR or socials.
Second, listen carefully to instructions. Those giving you work (supervisor, trainee buddy, etc) have limited time, so listening carefully and having a notebook at hand will help you remember what they have asked you to do, what to watch out for, what you may run into trouble with etc. It also helps you not look like a moron because you forget something and need to ask them again.
Third, be kind to your VS buddies you are all together on the VS and those evaluating you will see how you integrate. Yes you will have d**kheads who are gunning for the role and are selfish and whatever, just remember that they'll probably have a bad overall attitude (point 1) so they won't get the TC anyway. And if they do... then that's the luck of the draw, but having friends on the TC is very important, so better to build bridges. This also goes for group projects and negotiations and what not, make sure to involve everyone. They want to see a team player who is respectful.
Fourth, prepare for you interviews , I understand that the final interview can be stressful, but prepping really helps and you can ask your trainee buddy (or supervisor if you see they are not too busy) for some help or to ask you tricky questions. Don't obviously over prepare since you want to see the forest as a whole and not only singular trees but knowing the ins and outs of various practice groups, prepping questions for the partners and reflecting on the VS as a whole will really help you.
Fifth, work hard! Think of it like a 2 week interview. You'll have a mix of work given to you by your team, by GR for the assessment process or assessments in general (think group presentations, written evaluations, etc.) Each of these will form a part of the larger assessment process, so make sure to work on each as hard as possible. Obviously this point depends on firm to firm, so if your supervisor tells you to go home, go home. But if you're at a firm where this isn't really the case (WEIL lol) work your ass off, plan your days and get to the office early/on time, this will be evaluated. Planning is key, and it leads to effective prioritisation.
Sixth, dress well. Now I'm a guy so I can only speak from my own perspective, but when I mean dress well I don't mean the cost of your clothes or whatever, I am solely speaking about taking care of yourself. It may seem silly but brushing your hair, clean teeth, clean shaven or well groomed beard, neatly pressed shirt/suit and polished shoes can give you the small edge. Everyone is judged by their physical appearance and it would be a shame to create bias against yourself if you don't take care of yourself.
Finally, enjoy yourself. The reason you are doing the VS is hopefully because you want to, so take the 2 weeks as your opportunity to learn as much as possible, meet as many cool people on the VS cohort and the firm and get a feel for if you'd like to work there. You more than talented enough to get the TC so smile, focus and get that job you deserve!
