How to Pass the Conduct Software Engineer Interview in 2026
The Conduct DNA (TL;DR)
The Conduct Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard problems, reasoning about defects, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Conduct interview outcomes, avoid these common traps:
- Failing to connect personal career goals to the company's mission.
- Incorrectly handling the net displacement calculation.
- Not handling cases where one node is an ancestor of the other, or where nodes are not present.
- Not handling duplicate values correctly when removing or selecting randomly.

9 of 13 questions shown
Recruiter Screen
1- 1
Type · motivation
What specifically about Conduct's mission to improve developer productivity and collaboration resonates with you, and how does that align with your career aspirations?
Coding Screen
3- 2
Type · algorithm
Given a list of user sessions, where each session has a start and end timestamp, write a function to find the maximum number of concurrent active sessions at any point in time. Assume sessions can overlap. - 3
Type · data-structure
Implement a data structure that supports adding a number, removing a number, and returning a random number from the current set of numbers, all in average O(1) time. Duplicates are allowed. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · design
Design a system to track and display the real-time status of thousands of background jobs running across a distributed fleet of servers. Consider how to handle failures and ensure data consistency. - 5
Type · design
How would you design a rate limiter for an API that needs to support millions of requests per second, with varying limits per user and per API endpoint? Discuss trade-offs. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · algorithm
Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree. Assume all node values are unique. - 7
Type · debugging
You're given a function that's supposed to calculate the average session duration for users who signed up in the last 30 days. It's returning incorrect results. Here's the code [provide a buggy code snippet]. Debug and fix it. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
3- 8
Type · ownership
Tell me about a time you encountered a significant technical challenge or bug in a production system that was impacting users. What steps did you take to diagnose, resolve, and prevent recurrence? - 9
Type · collaboration
At Conduct, we often balance the need for extreme system reliability against the desire to ship features rapidly for enterprise clients. Describe a time you had to advocate for a specific technical trade-off that contradicted a product lead or another engineering team's priority. How did you quantify the impact of your proposed path versus the alternative, and how did you reach a resolution? - + 1 more questions in this round (sign up to unlock)

Frequently asked questions
How long does the Conduct interview process take?
Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.
How should I prepare specifically for Conduct?
Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.
Does this apply to engineering or design roles at Conduct?
The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.
