Practise answering 5 interview questions for E-Discovery Platform Engineer roles. Covers explaining deduplication nuance, document-count discrepancy investigation for opposing counsel, TAR 1.0 vs. CAL trade-offs, and defensible processing-pipeline rollout judgment.

1 / 5
The interviewer asks: "How would you explain to a litigation attorney why deduplication in an e-discovery platform is more complex than simply removing identical files?" Which answer best demonstrates clear communication?
Option B correctly explains why naive file-hash matching misses the real-world duplication patterns in email and document sets, and describes the actual technique, normalized-content hashing plus near-duplicate similarity scoring, that platforms use to handle it. The other options oversimplify or misstate standard e-discovery practice.
2 / 5
The interviewer asks: "A custodian's document count in the review platform dropped by 30% after a re-index, and opposing counsel is asking why. How do you investigate?" Which answer shows the most rigorous diagnostic thinking?
Option B checks for a legitimate deduplication scope change, reviews processing exception logs, and compares file-level manifests before ever responding to opposing counsel, producing a defensible, documented answer rather than guessing or conceding prematurely. The other options skip the rigor this scenario legally requires.
3 / 5
The interviewer asks: "What is the difference between technology-assisted review (TAR) 1.0 and continuous active learning (CAL) approaches, and when would you recommend each?" Which answer is most technically precise?
Option B correctly distinguishes TAR 1.0's fixed seed-set training from CAL's continuous retraining and prioritization, and gives a defensible recommendation tied to whether the document population and relevance criteria are stable or evolving. The other options misstate the underlying mechanics.
4 / 5
The interviewer asks: "How do you decide whether a new document-processing pipeline change is ready to roll out to a live, ongoing review matter versus needing more validation?" Which answer best demonstrates sound engineering judgment?
Option B validates against the actual matter's real document mix, does a side-by-side output comparison, and ensures defensibility documentation before rolling into a live matter — recognizing that unexplained processing differences carry real legal risk. The other options skip validation or start with the highest-risk matter first.
5 / 5
The interviewer asks: "Tell me about a time a processing bug in your e-discovery platform nearly caused a defensibility problem in a live matter. What was the outcome?" Which answer best follows a structured STAR approach with concrete detail?
Option B identifies a precise root cause (a silent PDF-extraction failure specific to one encryption method), a concrete systemic fix (an automated low-text-ratio validation check rather than relying on thrown exceptions), and a measurable, credible result (400 documents corrected before deadline, plus 15 further catches). The other options are vague or lack the technical specificity and quantified outcome.
