Hi!
I actually think that having a crystal-clear idea about
the one specific area you would want to practice in is not as common as you think!
Nevertheless, here's how I would approach this:
- If you are applying to a more general, full-service law firm, it's actually great to demonstrate that you have an open mind and are open to exploring different practice areas - you never know if you like something until you actually try it in practice! I would still, however, get an in-depth understanding of one or two practice areas that have caught your attention and be prepared to explain why you are potentially interested in experiencing them during your training contract.
- If you are targeting narrower, smaller firms with a clearly visible specialism (for example, PE), then I'd say having a clearly defined and well-evidenced interest in that practice is indeed necessary.
So, in short, I'd say that the degree of certainty in deciding which practice area appeals to you the most varies between firms. And, at the end of the day, one of the reasons that TCs with seat rotations exist in the first place is to provide you with an opportunity to make a conscious decision about where you qualify!
