Behavioral

Tell me about a time you worked under a tight deadline to deliver a financial model.
Situation

During my summer analyst program, the senior associate needed a three‑statement model for a potential acquisition within 48 hours.

Task

I was tasked with building a complete DCF‑based valuation and sensitivity analysis to support the pitch deck.

Action

I prioritized key drivers, used a modular Excel template, and leveraged VBA macros to automate repetitive calculations, while checking data integrity with the senior associate every 6 hours.

Early in my analyst career, I missed a regulatory filing deadline for a small private placement because I misinterpreted the jurisdictional requirements.

Task

Ensure all compliance documents were submitted on time to avoid penalties.

Action

After the miss, I conducted a root‑cause analysis, created a compliance checklist, and instituted a dual‑review process with senior associates for all future filings.
