It's exciting to see Saudi Arabia, hosting the 2034 World Cup. While such large events can create short-term opportunities (e.g., increased demand for project mgmt, infra development, strategic planning), I think it's crucial not to base your career strategy on them. These events can boost the economy and create temporary demand, but they shouldn't be the sole factor in your career decisions.
If you are still set on making your MBB entry I would focus on long-term career goals, like skill development, industry knowledge, networking while of course ensuring you have a strong academic record, relevant experience and a lot of prep.
I can help with the latter ;)
Best,
