How to prepare for the Wells Fargo interview

1. 1. Start at the top of the list above. The patterns are ordered by how often Wells Fargo uses them, so the first two or three buy you the most coverage per hour.
2. 2. Solve by pattern, not at random. Doing eight two pointers problems in a row is what makes the ninth recognisable in an interview — jumping between topics does not.
3. 3. Tick problems off as you go so the gaps are visible. The per-pattern counts tell you which Wells Fargo topic you have actually covered.
4. 4. Write the approach before the code. Wells Fargo interviews are judged on the reasoning as much as the working solution.
5. 5. Pair this with the pattern guides when a topic is new, and the system design sheet if the role is senior enough to have that round.
6. 6. If this is a campus or off-campus drive rather than a lateral move, the placement preparation guide covers the stages around the DSA round — aptitude, core subjects and the HR interview — in the order they actually happen.
