One customer endpoint stalls deliveries to every other destination
The egress service delivers about 1.5k webhooks/second across 40,000 destinations, with a per-destination concurrency cap of 4 and a 10-second connect-plus-read timeout. Throughput falls to 300/second, queue depth climbs, and p99 delivery latency for unaffected destinations goes from 200 ms to minutes, while the error rate barely moves. One tenant holds 900 destination rows whose URLs share a hostname that now answers in 9.5 seconds. Explain the mechanism with the arithmetic, then give the containment in the order you would apply it.
Approach
- Look at saturation before errors. A flat error rate with collapsing throughput says nothing is failing, things are waiting, so the first signal to pull is in-flight request count or pool wait time rather than the error counter. This is the distinction that decides the whole investigation.
- Group in-flight work by resolved host, not by destination id. The cap is keyed per destination row, so 900 rows sharing one hostname buy 3,600 concurrent slots against a single host, each held for 9.5 seconds. The bulkhead was never a bulkhead for that host, and grouping by the wrong dimension is why the dashboard looked healthy.
- Do the arithmetic in both directions. Required concurrency is arrival rate times latency, so 1.5k/second at 200 ms needs about 300 in flight, which is entirely consumed by 3,600 slow slots; conversely whatever concurrency is left sustains rate equals concurrency divided by 9.5 seconds, which is the 300/second you are seeing. Matching both numbers is what promotes this from a plausible story to the mechanism.
- Explain why the circuit breaker never helped. It opens on consecutive failures, and a 9.5-second response inside a 10-second timeout is a success. Slow is not failing, so an error-rate breaker cannot see this; you need a slow-call ratio, a deadline propagated from the caller's remaining budget, or a concurrency limiter.
Follow-up
- The host recovers to 80 ms. How long does the queue take to drain, and what does the drain do to the recovered host?
- Where should the 10-second timeout number actually come from?

How long does the interview process typically take?
While the process is generally efficient, it can vary by team and location. Expect the entire cycle to range from a few weeks to a couple of months.
Odoo Software Engineer candidate reports ↗What is the most common reason for rejection?
Many candidates struggle with the technical assessment or fail to demonstrate a deep understanding of the fundamentals (like SQL or OOP concepts) during the final rounds.
Odoo Software Engineer candidate reports ↗Is the technical interview purely LeetCode?
Not entirely. While you will face algorithm problems, you will also be tested on database design and system concepts, which are equally important for the Odoo platform.
Odoo Software Engineer candidate reports ↗Are remote tools allowed during the technical round?
Expect to code in a live environment. You are generally expected to solve problems without relying on AI tools or extensive external documentation.
Odoo Software Engineer candidate reports ↗What topics does Odoo test in interviews?
Odoo interviews most often cover Data Structures & Algorithms (DSA), Inventory Management Concepts, SQL, Systems Thinking, and JavaScript (JS). The exact emphasis depends on the specific role you apply for.
