Hi!
This is completely normal, and I felt exactly the same before my first vacation scheme. I remember in the days leading up to it I felt properly sick with nerves, and it wasn't the kind of anxiety that you can logic your way out of (as my nervous system seemed to be ignoring my brain!). I think it is because it does feel like there is a lot riding on that one or two weeks, so the pressure can build up quite a bit beforehand.
However, what helped me with my later schemes is that I realised it changes once you are actually there on the scheme. As soon as you get into the firm, start chatting with the graduate recruitment team and other vacation schemers, and get to know your team, the nerves do start to ease quite quickly. You are usually so busy with inductions, talks, work tasks, and social events so you don't have much time to sit and overthink everything. Everyone at the firm is super supportive and genuinely wants you to succeed, so it is definitely more encouraging once you are there!
It is also worth remembering that firms do not expect you to come in knowing everything or be "perfect". The scheme is designed for you to learn and get exposure, and they are much more interested in how you approach things. For example, are you engaged with the tasks and people on the scheme? Do you show curiosity and ask questions? Are you proactive and pleasant to work with? Those things matter far more than getting every task exactly right.
It also helped me to reframe it slightly, and instead of seeing it purely as an assessment, try to treat it as an opportunity to figure out whether you like the firm as well. That shift in mindset can take a bit of the pressure off and make it feel more like a two-way process. I think it is very easy to spiral about things such as conversion rates and whether you'll receive a TC offer at the end, which is completely valid, but even if it doesn't work out the way you'd like it to, it is still amazing experience. You are clearly a strong candidate if you are capable of receiving a VS offer, so there is no reason why you wouldn't have more success in the future too!
Practically, a few other things that helped me feel 'prepared' when it felt like I couldn't do much in advance:
- Having a rough understanding of the firm and (if you know it in advance) the team you'll be in. However, don't panic about trying to know absolutely everything about the team - aim for a baseline understanding, and you'll learn the rest on the scheme.
- Preparing a few questions in advance so that you are not put on the spot
- Reminding yourself that everyone else on the scheme is probably feeling very similar, even if they don't show it.
The anticipation is honestly the worst part - once you are in it, it feels so much more manageable than you expect (and I genuinely enjoyed all of my vacation schemes!).
You are definitely not alone in feeling like this, and the fact that you care this much is a good sign (as it shows you'll do your best!). The nerves will settle once you get started, so I would try to take it one day at a time and be kind to yourself over the next few days.
Wishing you the very best of luck - I'm sure you'll smash it!!
