What to do if no offers?

I am recruiting now for London SA 26, but I am getting the feeling that I won't be getting any offers. For context I had top grades in my bachelor, am now in one of the top target unis in Europe, have previous experience in consulting and corporate banking. I didn't think that getting through the first screening rounds would be this hard (how do 2nd year bachelors in the UK do it????), and it seems like unless I have several MBB, IB and PE internships, there is almost no point in even applying.

My question is then, what is there even to do? This whole process has genuinely felt like such a waste of my life, and I feel like I am going to graduate with little to show for it.
