• Collaborating With and Helping an ML Engineer as an ML Infrastructure EngineerMedium

  A behavioral cross-functional collaboration question for a software engineer on a machine learning infrastructure team, posed by an ML engineer who uses the platform. It tests how you would discover an internal customer's needs, agree on priorities, communicate through changes and failures, and help them succeed.

• Data quality, lineage, monitoring and backfill design for an ML feature storeMedium

  A discussion-based ML infrastructure design round on keeping the data behind models reliable and well governed. It covers defining and measuring availability, freshness, completeness, validity, consistency, distribution, compliance and lineage, monitoring a feature store, and planning a safe, correct data backfill.

• Design a product likes system for a marketplace of brands and retailersMedium

  Design the backend for product likes on a marketplace where retailers like or dislike products, list the products they liked and see like counts in search results, while brands see the likes on their own products. Tests data modeling for two access directions, counter maintenance, idempotent writes and scaling the search read path.

• Design a real-time model inference platform: deployment, scaling and monitoringMedium

  An ML system design question asking for a real-time model inference platform that teams use to serve trained models inside their applications' request paths. It tests safe model deployment and rollback, per-model autoscaling and batching, failure handling, and monitoring from infrastructure up to model quality.

• Find first 5-7-5 haiku in sentenceMedium

  Find first 5-7-5 haiku in sentence evaluates algorithm design, data structures, correctness, complexity, edge cases, and implementation details in a realistic interview setting. A strong answer states assumptions, handles edge cases, explains trade-offs, and shows how to validate the result clearly.

• Max inherited discount and discount-source audit in a category DAGMedium

  A two-part coding problem on an e-commerce category hierarchy shaped as a DAG, where a product's applied discount is the largest discount on its category or any ancestor. The follow-up asks for an audit of which discounted categories appear in the ancestry of each bottom-level category, testing traversal order, deduplication and shared work.

• Peak number of bikes needed to cover all pre-booked rental intervalsMedium

  Given every booking for a bike rental service as a start and end time, compute the peak number of bikes in use at the same moment, which is the smallest fleet that serves all bookings. Tests interval-overlap reasoning, half-open boundary handling and an efficient method for up to 100,000 unsorted bookings.

• Validate assumptions and align stakeholders for a new user-permission featureMedium

  An engineer is asked how to validate the assumptions behind a new feature that changes a product's user permission model and how to reach agreement with stakeholders such as security, support and sales. Tests risk-ranked validation, safe migration of existing access, staged rollout, and turning disagreements into clear decisions.
