Frequently asked questions
- What does the Observability check test?
- The check covers metrics, logs, traces, slos, alerting, distributed tracing, opentelemetry. Questions span beginner to advanced difficulty and test both conceptual understanding and practical trade-off reasoning.
- What keywords should I know for Observability?
- Key concepts include: observability, metrics, logs, traces, slo, sli, prometheus, opentelemetry, alerting. These frequently appear in system design interviews at product and infrastructure companies.
- How many questions are in the check?
- Each check has 10 questions — a mix of MCQ and short-answer. You get scored by dimension (e.g., scalability, consistency) so you know exactly where to focus.
- How long does it take to study Observability?
- Most engineers spend around 3 hours on this module. The check itself takes about 10–15 minutes. You can retake it up to 3 times per day.
- What prerequisite knowledge do I need before Observability?
- Observability builds on Microservices and Reliability. Complete those first for the best results.
- Is observability, metrics, logs covered?
- Yes. The Observability module covers observability, metrics, logs among other key concepts. The check includes questions that reflect real system design interview patterns.
