- Front
- What do you do when asked for a number you never measured?
- Back
- Be honest that it is unmeasured, separate a target from a result, and name the measurement you would add, such as a per-stage trace.
- Front
- When does a rank-1 document from one list beat a document with the same rank in both?
- Back
- With k = 60, when that shared rank r is above 62: 1/61 beats 2/(60 + r). At r = 62 they tie. Fusion rewards agreement but does not guarantee it wins.
- Front
- Can a document in only one list beat a document in both lists under RRF?
- Back
- Yes. With k = 60, first in one list scores 1/61 = 0.0164, while 70th in both scores 2/130 = 0.0154. Agreement helps, but it does not override a very weak rank.
- Front
- How do you label a number in a project defense?
- Back
- Measured, estimated or unknown. For an unknown, say so and name the measurement you would add.
- Front
- Four behavioural stories to prepare for a GenAI role?
- Back
- A quality regression you diagnosed, a latency versus quality trade-off, a time you pushed back on an LLM where something simpler worked, and a time you managed expectations about hallucinations.
- Front
- What are the three mock rounds?
- Back
- Round 1: questions (Drills A and B). Round 2: an unseen design prompt (Drill C). Round 3: project defense plus coding (Drills D and E).
