Defend Your Own Research Paper: Experimental Setup, Practicality and Later Work
Company: Cohere
Role: Machine Learning Engineer
Category: Machine Learning
Difficulty: medium
Interview Round: Onsite
In a research paper round, you present one of your own published papers. Assume the interviewer already knows the paper well. They may skip your prepared slides entirely and go straight to its weaknesses. Expect questions such as:
- Was your experimental setup reasonable? Where is it weakest?
- Are the results practical, that is, would they hold up and be useful outside the paper's setting?
- What major developments has the field seen since the paper was published, and how do they affect your conclusions?
This round is not a reading-group walkthrough of the paper's content. Prepare the presentation and your answers so that they hold up under this kind of questioning.
```hint Critique it first
Before the interview, list every choice in your experimental setup that a skeptical reviewer would question, and decide what evidence you have for or against each one.
```
```hint Since publication
For the question about later developments, look for later work that changed a baseline, a benchmark, a scale or an assumption your paper relied on.
```
### Clarifying Questions
- How long is the round, and how is it split between presentation and questions?
- Should the paper be related to the team's area, and is co-authored work acceptable if you explain your own contribution?
- Are slides expected, or is a whiteboard discussion equally acceptable?
### What a Strong Answer Covers
- A short, precise statement of the problem, the contribution and the main evidence
- A specific, honest critique of the experimental design: baselines, data, metrics, ablations, variance and compute
- A clear line between what the evidence supports and what it does not
- An assessment of practical value: cost, scale, robustness and deployment constraints
- Awareness of later work, and whether it strengthens, weakens or supersedes the paper's claims
- Your own role in the work, and composure when the prepared structure is abandoned
### Follow-up Questions
- If you could rerun one experiment with unlimited compute, which would you choose, and what result would change your mind?
- Which later result most threatens your paper's main claim, and how would you respond to it?
- How would the method or its lessons apply to post-training a large language model?
- If you wrote the paper today, what would you change in the evaluation?
Overview: A research paper round where you present your own published paper to an interviewer who already knows it and questions its weaknesses. Prepare to judge whether the experimental setup was reasonable, whether the results are practical, and what the field has learned since publication, all with specific, honest self-critique.
