Question 1

Tell me about a time you fundamentally disagreed with a senior engineer or manager on a technical design. How did you handle it?

Accepted Answer

Bar Raisers want to see that you will speak up when something is wrong, even to authority figures, AND that you can do so with data and respect — not ego. They also want to see that you will fully commit once a decision is made, even if it is not yours. Principle: Have Backbone; Disagree and Commit. Structured using Situation, Task, Action, and Result for SDE1 through Principal engineering levels.

Question 2

Tell me about the most complex technical problem or operational crisis you have ever had to resolve.

Accepted Answer

This question tests whether you can hold the full complexity of a production system in your head, stay calm under pressure, lead others, and drive to the root cause rather than treating symptoms. Bar Raisers look for methodical debugging, not lucky guessing. Principle: Ownership · Dive Deep · Bias for Action. Structured using Situation, Task, Action, and Result for SDE1 through Principal engineering levels.

Question 3

Describe a time you had to deliver a project under an impossibly tight deadline or significant constraints. What trade-offs did you make?

Accepted Answer

This question reveals how you think about prioritization, scope negotiation, and managing technical debt intentionally. Bar Raisers want to see that you can ship under pressure WITHOUT creating hidden landmines — and that your trade-offs were conscious and documented, not just corners cut blindly. Principle: Bias for Action · Deliver Results · Frugality. Structured using Situation, Task, Action, and Result for SDE1 through Principal engineering levels.

Question 4

Tell me about a time you identified a major risk or problem before it became a crisis, and what you did about it.

Accepted Answer

Bar Raisers are looking for engineers who act like owners of the entire system, not just their assigned ticket. This question identifies whether you proactively look for risks in things you do not directly own — and whether you do something about it even when it is not your job. Principle: Ownership · Invent and Simplify · Are Right, A Lot. Structured using Situation, Task, Action, and Result for SDE1 through Principal engineering levels.

Question 5

Tell me about a time you had to work on a project with vague or constantly changing requirements with no clear technical direction.

Accepted Answer

Bar Raisers want to see that you do not freeze or complain when requirements are unclear. They evaluate whether you can create clarity from chaos by writing RFCs, building fast prototypes, defining boundary constraints, and iteratively aligning stakeholders. Principle: Are Right, A Lot · Deal with Ambiguity · Invent and Simplify. Structured using Situation, Task, Action, and Result for SDE1 through Principal engineering levels.

Question 6

Tell me about a time you drove an engineering initiative or mentored team members to significantly elevate engineering standards and velocity.

Accepted Answer

Bar Raisers evaluate how you multiply the impact of engineers around you. True senior/principal engineers do not just write great code themselves — they raise the bar for the entire organization through mentorship, tooling, and establishing culture. Principle: Earn Trust · Develop the Best · Insist on the Highest Standards. Structured using Situation, Task, Action, and Result for SDE1 through Principal engineering levels.

Question 7

Tell me about a time you advocated for the customer when technical or business priorities were pushing in a different direction.

Accepted Answer

Bar Raisers look for engineers who start with the customer and work backwards. They evaluate whether you prioritize long-term user trust and experience over short-term engineering convenience or aggressive business metrics. Principle: Customer Obsession · Insist on the Highest Standards · Earn Trust. Structured using Situation, Task, Action, and Result for SDE1 through Principal engineering levels.
