Architecture & trade-offs
A broad, senior-to-staff loop that lives in the grey areas: no single right answer, just choices and the reasons behind them. You'll move across data, APIs, and real-time, and the interview is really about your judgment under ambiguity.
- System design
- Data
- APIs
- Trade-offs
Interview flow
A style plays out as a sequence of sessions — start each one on its own; your readiness rolls up across them.
- 1. Depth interviewA broad architecture round centred on trade-offs and judgment.Start below
What interviewers usually probe
- Why this design and not the obvious alternative.
- Where consistency, latency, and cost pull against each other.
- How the system fails, and what you'd give up to keep it up.
- The second-order effects of a choice three months later.
What we assess
- System design reasoning under ambiguity
- Data and API architecture choices
- Consistency, latency, and cost trade-offs
- Judgment and justification, not recall
What we don’t
- Framework-specific triviaThis style stays at the architecture altitude. For hands-on depth, pick a language- or framework-focused style.
- Algorithmic (DSA) roundsNo coding puzzles — this is a design and judgment loop.
