Say this
There is no clever answer to this one. You either know the levels or you do not, and not knowing them tells the interviewer you do not follow markets.
Then walk it
- Know the index level and the direction of the last session. Approximate is fine; blank is not.
- Know the 10-year Treasury yield, the policy rate, oil, gold, and the dollar index. For an India-facing interview, add the Nifty, the 10-year G-sec and the rupee.
- Have one sentence on why the market moved. 'Equities were up on a softer inflation print and the 10-year fell about five basis points' is a complete answer.
- If you genuinely do not know, say so once, quickly, and give the level you last checked with the date. Do not guess a precise number.
- Build the habit rather than cramming: five minutes a morning on one market wrap for the two weeks before you interview is enough.
Where candidates lose it
Guessing a precise number and being wrong. That is worse than admitting you have not checked since yesterday. Interviewers on trading floors do this specifically as a preparation test, and they already know the answer.
Expect next
- Why did it move?
- What is X commodity trading at?
- What do you think the index closes at by year end?

Firm tags come from public, anonymous candidate reports on Wall Street Oasis: strong signal, not sworn testimony. Firms are named as the places a question was reported, not as partners of Fin Maverick. Answers are written for this page to show how to think out loud; they are not scripts to recite.
