London hiring rewards focus. Prep two weeks of DSA before applying to big tech and quant firms — their loops are algorithm-heavy. For fintech and product scale-ups, a clean system-design story and one well-built project matter more than LeetCode volume. Confirm visa sponsorship early if you need it, and lean on referrals: a warm intro through LinkedIn dramatically outperforms cold applications.
