How long does the Seed digital 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 Seed digital?

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 Seed digital?

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.

Coding Screen
LeetCode-medium algorithmic problems under time pressure.
3
Round 3
System Design
Distributed systems, trade-offs at scale, architecture under constraints.
4
Round 4
Onsite Coding
LeetCode-hard, debugging, code clarity, edge cases.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Seed digital interview outcomes, avoid these common traps:

Not demonstrating an ability to understand or empathize with the other party's perspective.
Not demonstrating a clear resolution or positive outcome.
Failing to articulate the specific steps taken to build consensus or address concerns.
Not detailing the specific tactics used to influence others (e.g., data, empathy, compromise).

Test Yourself: Real Seed digital Questions

Three real prompts pulled from our database.

Type · Influence

Describe a situation where you had to influence a stakeholder or team to adopt your idea or approach, especially when they were initially resistant.

Type · Past Experience

Tell me about a time you had to influence a cross-functional team (e.g., engineering, sales, marketing) to adopt a new product or strategy they were initially resistant to. What was your approach, and what was the outcome?

Type · Behavioral

Tell me about a time you had to work with a difficult stakeholder (e.g., product manager, designer) to deliver a feature. How did you manage the relationship and ensure the project's success?

Recruiter Screen

1
Type · Motivation
What interests you about working at Seed Digital, specifically within the advertising technology space, and how do you see your skills contributing to our growth?

Coding Screen

2
Type · Algorithmic
Given a stream of ad impression events, each with a timestamp and a user ID, design an algorithm to calculate the number of unique users who saw an ad in the last hour. Assume the stream can be very large.
3
Type · Algorithmic
You have a list of user segments and a list of ads. Each ad can be targeted to multiple segments. Write a function to find all ads that can be shown to a given user, based on the segments the user belongs to.

4
Type · System Design
Design a real-time bidding (RTB) system for ad impressions. Consider the components involved, data flow, latency requirements, and scalability.
5
Type · System Design
Design a system to track ad campaign performance and generate reports. What data would you collect, how would you store it, and how would you process it for reporting?

6
Type · Algorithmic
Given a list of user IDs and their associated conversion events (e.g., purchase, sign-up), write a function to calculate the conversion rate for a specific campaign. Ensure your code is clean, handles edge cases, and is well-tested.
7
Type · Debugging
A user reports that ads are not displaying correctly for a specific segment. Here's a simplified version of the ad selection logic. Find and fix the bug.
