Primary hiring signals

  • scalable systems
  • real-time data thinking
  • execution

Phone screen

  1. Recruiter screen often checks scope, leveling, and domain fit.
  2. Technical phone typically covers coding or SQL plus data architecture for high-scale systems.

Full interview loop

  1. Recruiter and technical screen.
  2. Onsite rounds often mix coding, SQL, distributed data design, and system reliability.
  3. Behavioral interviews emphasize execution, ownership, and decision making under pressure.

How much prep time is required?

5-7 weeks, especially if streaming/event-time concepts are not already second nature.

How to prepare

  • Practice system design for near-real-time pipelines, SLAs, retries, and event-time correctness.
  • Prepare stories where you delivered under urgency without breaking quality.
  • Review operational trade-offs: latency, reliability, and oncall-style debugging.

First 5 behavioral prompts to rehearse

  1. Tell me about a time you improved reliability under pressure.
  2. Describe how you prioritized multiple urgent asks.
  3. Tell me about a technical debt call you made.
  4. Describe a time you simplified a complex system.
  5. Tell me about a postmortem that changed your team behavior.

Pair this with the Behavioral track, then run two timed mock loops using these prompts + one SQL + one system-design round.

Also keep one primary technical track active: System Design or Coding. This avoids context-switching and keeps weekly prep focused.
