The Seyna DNA (TL;DR)
Embedded Protection Insurance and Pet Insurance products require candidates to break down complex underwriting rules into clear operational specs. Evaluators watch for explicit trade-offs when designing API-first policies and precise metric denominators during product stress tests.

The Seyna 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 Seyna interview outcomes, avoid these common traps:
- Proposing a monolithic calculation engine without considering distribution or parallelization.
- Not handling out-of-order updates correctly, leading to stale data.
- Expressing frustration or negativity towards the legacy system.
- Incorrectly implementing the time window logic (e.g., fixed vs. sliding window).
Test Yourself: Real Seyna Questions
Three real prompts pulled from our database.
Type · behavioral
Tell me about a time you had to work with a complex, legacy codebase. How did you approach understanding it, making changes, and ensuring the stability of the system?
Type · coding
Implement a function that takes a list of insurance claims, each with an amount and a status (e.g., 'pending', 'approved', 'rejected'), and returns the total approved amount for each claim status. Handle potential malformed data gracefully.

System Design
3- 4
Type · system-design
Design a system to detect and flag potentially fraudulent insurance claims in real-time. Consider data sources, processing, and the trade-offs between accuracy, latency, and cost. - 5
Type · system-design
Design an API for managing insurance policy endorsements. Consider different types of endorsements (e.g., adding/removing coverage, changing policyholder details), versioning, and idempotency. - + 1 more questions in this round (sign up to unlock)

Onsite Coding
3- 6
Type · coding
Implement a function to simulate the process of underwriting a new insurance application. The function should take applicant data and a set of underwriting rules, and return an approval decision with a calculated risk score. Handle complex conditional logic and potential data inconsistencies. - 7
Type · coding
Given a nested data structure representing an insurance policy's coverage breakdown (e.g., 'auto': {'collision': 500, 'liability': 1000}), write a function to flatten this structure into a list of key-value pairs, summing up values for duplicate keys at the same level. - + 1 more questions in this round (sign up to unlock)

Type · behavioral
Tell me about a time you had to work with a complex, legacy codebase. How did you approach understanding it, making changes, and ensuring the stability of the system? - 9
Type · behavioral
At Seyna, we balance the need for rapid feature deployment to our insurance partners with the strict reliability requirements of core underwriting systems. Describe a recent instance where you had to advocate for slowing down a release to improve technical stability, and how you communicated this trade-off to non-technical stakeholders like product managers or commercial teams. - + 1 more questions in this round (sign up to unlock)

Frequently asked questions
How long does the Seyna 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 Seyna?
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 Seyna?
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.
