When a Resume Lacks Highlights, How to Probe Basic Knowledge in Interviews

If a candidate’s résumé contains no clear highlights, the interviewer should try to uncover hidden strengths by asking probing questions about past difficulties.

"If HR sends a resume with no highlights, I can only ask basic knowledge, there's nothing else I can do."

The interviewer first asks a broad question such as, "What was the biggest problem you faced at your last company, and how did you solve it?" This encourages the candidate to reflect on significant experiences.

When candidates hesitate, the interviewer can suggest specific types of challenging situations to trigger responses:

Solving a particular technical problem.

Fixing a hard‑to‑reproduce bug.

Delivering a requirement under extremely tight deadlines.

Leading the design of a complex module.

Optimising an API response from seconds to milliseconds.

Refactoring a complex module from 0 to 1.

Doubling team productivity or throughput after joining.

…and other similar achievements.

These prompts usually give the candidate a direction to answer.

The reason for asking such questions is that tackling difficult problems involves decision‑making, trade‑offs, and measurement; the process of solving them fosters growth.

During the discussion, the interviewer probes the details of the solution because sometimes the candidate may not have been directly responsible for the outcome. Detailed follow‑up helps verify genuine involvement.

If the candidate cannot provide a satisfactory answer, the interviewer falls back to basic technical questions.

"The purpose is to see whether the candidate is truly interested in technology."

The interviewer assesses whether the candidate has studied underlying principles or merely used the technology superficially. If the candidate shows no depth, they are considered a poor match.

The author concludes that a résumé must contain highlights; otherwise, interviewers will inevitably focus on basic details. For seasoned professionals who have led core modules for years, the interview strategy and focus would be entirely different.
