IB is way easier than Law in terms of the process getting started. Law is demotivating because you don't even get responses from firms if they're not interested - at least in IB, those rounds give you a chance to at least explain why you're suited.😣 fr they just keep adding more and more rounds with each application cycle... soon we'll be on par with IB with 5-6 interview rounds after all the crazy tests and hirevues haha...
For Law, you have to do detailed research, pour over things and then you get rejected anyway because your cover letter was too generic. And the module grades seem to matter so much for Law whereas IB doesn't care as long as it's a 2:1.
For IB, all you have to do is write a generic cover letter, mention a specific deal they worked on and why you liked it, and then praise the firm for either being big (so 'more complex deals') or small ('not being a cog in a machine').
You do that and you can get interviews from many firms. I had lots of IB interviews and my cover letters were so generic.
