Embeddings Capacity Interval Planner

AI/ML Engineer signal: line sweep + interval merge in a embedding drift monitor context. This is a ProdMatch-owned ai ml engineer drill, framed as a May 2026 Myntra Model Observability simulation, not a copied platform question.

Product surface

embedding drift monitor

ProdMatch interview simulation based on product-team patterns; not a claim of a real company question.

Question

Plan capacity for embedding drift monitor. Given reservation intervals with requested units, return the minimum capacity needed and all time ranges where capacity crosses a critical threshold.

Input

Intervals [start, end, units] and threshold.

Output

Peak capacity and merged high-pressure intervals.

Constraints

1 <= intervals.length <= 200000
Intervals are half-open: [start, end).
Timestamps fit in signed 32-bit integers.

Concepts

vector search
RAG retrieval
recommendation graphs
line sweep
interval merge
capacity planning

[[1,4,3],[2,5,4]], threshold=6 -> peak=7, hot=[[2,4]]

Approach

Try framing your own approach first. The 30 seconds you think before peeking is where learning happens.

Clean Solution

Reveal the approach first.

How well did you understand?

Your rating tunes when this problem shows up again.

Common Mistakes

Be explicit about whether touching endpoints overlap.
Process end events before start events for half-open intervals.
