**TL;DR —** Sysdig interviews test cloud-native security depth: expect to explain container and Kubernetes runtime detection, threat response in short-lived environments, and how you'd secure workloads from build through runtime. Technical rounds often draw on Falco and syscall-level detection, CNAPP topics like CSPM, CIEM, and vulnerability management, plus system design for spotting threats at scale, while behavioral rounds probe incident response and how you work across security and engineering teams. Tailor your prep to the specific role, since detection engineering, backend, and solutions positions each weight these areas differently.

Sysdig is one of the leaders in cloud-native security and observability — runtime security for containers and Kubernetes, plus monitoring. Built on the open-source Falco project. The interview is systems-heavy and rewards engineers with deep Linux internals knowledge.

## Process

Recruiter screen → 60-minute coding phone ([medium DSA](/problems-by-difficulty/) + systems trivia) → onsite virtual: 2 coding, 1 [system design](/category/system-design/), 1 craft deep-dive, 1 [behavioral](/post/3233460379/behavioral-interview-questions-2026-star-method-amazon-leadership-principles-and-winning-answers/). Cycle: 3–4 weeks.

## What they actually ask

- Design a runtime security agent that monitors syscalls in containers. Focus on how you capture syscalls without wrecking performance — the tradeoff between a loadable kernel module and eBPF probes, and how you map each event back to a container using its cgroup and namespace IDs. Interviewers probe how you filter noise in-kernel and what happens when events drop under load.

- Design eBPF-based instrumentation for security and observability. Be ready to explain what eBPF can and can't do safely: the verifier, bounded loops, maps for passing data to userspace, and why it's safer than a kernel module you can crash the box with. Expect follow-ups on attaching to tracepoints versus kprobes and the overhead of each.

- Design ingest at 1M events/sec for security telemetry. Talk through batching, backpressure, and partitioning — how you shard the stream, buffer with a queue like Kafka, and shed or sample load when consumers fall behind. They want to see you reason about the per-event CPU and memory budget at that volume, not just draw boxes.

- Coding: medium-hard DSA, often with concurrency or systems framing. Expect problems dressed in systems terms — a rate limiter, an LRU cache, a thread-safe queue, or parsing and aggregating an event stream. Practice the common [coding patterns](/algorithm-patterns-cheat-sheet/) and be ready to reason about locks, channels, or lock-free structures, not just the raw algorithm.

- Behavioral: ownership, working with security domain, deep technical work. Bring stories where you owned a gnarly systems problem end to end and shipped it. Have one concrete debugging example — a kernel panic, a race condition, a production incident — and be specific about the security stakes and how you weighed them.

## Prep priorities

- Be fluent in C/C++ (Falco core) and [Go](/post/3233474456/go-golang-interview-questions-2025-goroutines-channels-interfaces-error-handling-context-generics-concurrency-patterns/) (control plane). Falco's syscall processing and drivers are C/C++, while the orchestration and API layer lean on Go, so expect to read and reason about both. Know memory management and undefined behavior in C++, and goroutines and channels in Go.

- Understand Linux internals: syscalls, namespaces, cgroups, eBPF. This is the heart of the interview — know how a syscall crosses the user/kernel boundary, how namespaces and cgroups isolate a container, and where eBPF hooks in. Be able to explain what a container actually is at the kernel level.

- Brush up on Kubernetes security and runtime threats. Know the runtime threat model — container escapes, privilege escalation, crypto-mining payloads — and how a tool like Falco detects them from syscall patterns. Familiarity with pod security, RBAC, and admission control helps.

## Frequently Asked Questions

### Is Sysdig remote-friendly?

Hybrid in San Francisco, Belgrade, others. Many engineering roles remote within US/EU.

### How does Sysdig compare to Wiz or Aqua Security?

Wiz is broader cloud security; Sysdig deeper on runtime/container security; Aqua is the older incumbent. Sysdig pays comparably to Wiz for deep-systems engineers.

### What is the engineering culture?

Deep-systems oriented. Strong contributors to open-source (Falco, sysdig). Slower hiring but rigorous.
