Prepare 3 specific achievement stories with numbers

Every behavioural question ("tell me about a challenge you faced") can be answered with a prepared story. Use the STAR format — Situation, Task, Action, Result. The key is the result must have a number: "increased site visits by 40%", "reduced joining-to-departure time from 3 months to 6 weeks", "closed ₹80L worth of deals in Q3". Stories without numbers sound like opinions.
