This is not true!! Don't let the doom and gloom get to you.I don't want to sound like a doomer, but I've recently come to the realisation that the content of our application answers doesn't matter. These answers often just act as a filter for the other parts of your candidate profile.
Obviously I can't share these but, I have an old friend's successful applications from his second year of university. Trust me when I tell you that he essentially copy/pasted the exact same application for every firm he applied to – even down to using the same adjective for each of these firm's cultures. They were absolutely indistinguishable. However, this guy was on track to getting a first, he held multiple executive (society) positions, and he had also secured a large number of first-year schemes. If anybody else had written those applications, they would have been binned. But, his candidate profile was genuinely so impressive that (in my opinion) firms were willing to look past the lack of substance in his application answers.
Firms take holistic approaches to applications, sure there may be some firms who put a stronger emphasis on grades but many firms do not. I secured a TC at a top US firm without ever even getting a first in any module and only one vac scheme before
Quality applications and a genuine interest in the firm do actually make a difference, despite how hard that might be to believe because of how alienating the process feels.
