How to Pass the Aikido Security Software Engineer Interview in 2026

The Aikido Security DNA (TL;DR)

Aikido Security values candidates who demonstrate strong problem-solving skills, proactivity in identifying and mitigating security risks, and a deep understanding of modern software development and security best practices. They seek individuals who can contribute to a fast-paced, security-focused SaaS environment.

The Aikido Security Interview Loop

Your onsite loop will typically consist of 5 rounds.

  1. 1

    Round 1

    Recruiter Screen
    Motivation, role fit, logistics.
  2. 2

    Round 2

    Coding Screen
    LeetCode-medium algorithmic problems under time pressure.
  3. 3

    Round 3

    System Design
    Distributed systems, trade-offs at scale, architecture under constraints.
  4. 4

    Round 4

    Onsite Coding
    LeetCode-hard, debugging, code clarity, edge cases.
  5. 5

    Round 5

    Behavioral / Leadership
    Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Aikido Security interview outcomes, avoid these common traps:

  • Not demonstrating an understanding of the stakeholders' underlying motivations or concerns.
  • Describing a situation where the conflict was never truly resolved.
  • Not designing for idempotency in the ingestion pipeline, leading to duplicate data.
  • Giving a generic answer not specific to Aikido or the SaaS security space.

Test Yourself: Real Aikido Security Questions

Three real prompts pulled from our database.

Type · Algorithmic

Implement a function that takes a list of API request logs (each with a user ID, timestamp, and endpoint) and detects potential brute-force login attempts. Define 'brute-force' as more than N failed login attempts from the same user within a T-second window. Return a list of user IDs exhibiting this behavior.

Type · System Design

Design a notification system for Aikido Security that alerts users about critical security findings or policy violations. Consider different notification channels (email, Slack, in-app), user preferences, and ensuring reliable delivery. How would you handle potential scaling issues if millions of alerts need to be sent?

Type · Conflict Resolution

Tell me about a time you had a significant disagreement with an engineer or designer about a product decision. How did you approach the situation, and what was the outcome?

  1. 2

    Type · Algorithmic

    Given a list of security vulnerability findings (each with a severity level and a timestamp), write a function to return the top K most severe vulnerabilities, prioritizing newer ones in case of a tie in severity. Assume severity is an integer (higher is more severe).
  2. 3

    Type · Algorithmic

    Implement a function that takes a list of API request logs (each with a user ID, timestamp, and endpoint) and detects potential brute-force login attempts. Define 'brute-force' as more than N failed login attempts from the same user within a T-second window. Return a list of user IDs exhibiting this behavior.

  1. 4

    Type · System Design

    Design a system that can ingest security scan results from various sources (e.g., code scanners, dependency checkers, cloud config tools), deduplicate findings, enrich them with context (like affected codebase, severity), and present them in a unified dashboard for a SaaS customer. Consider scalability, reliability, and data consistency.
  2. 5

    Type · System Design

    How would you design a rate limiter for the Aikido API to protect against abuse and ensure fair usage for all customers? Discuss different algorithms (e.g., token bucket, leaky bucket, fixed window, sliding window log) and their trade-offs in a distributed SaaS environment.

  1. 6

    Type · Algorithmic

    Implement a function to parse and normalize vulnerability data from different security tools. Given a JSON input representing findings from Tool A, transform it into Aikido's standard internal format. Assume Tool A's format has nested structures and varying field names for severity and vulnerability type. Write clean, well-tested code.
  2. 7

    Type · Debugging

    A customer reports that their security dashboard is showing incorrect counts for 'High' severity vulnerabilities, specifically for findings related to container misconfigurations. The backend service responsible for aggregating these counts seems to be underperforming under load. Debug this hypothetical issue. What steps would you take, what tools might you use, and what potential causes would you investigate?
