System design

Work through a notification service, including capacity and failure behaviour.

A moment to rehearse

Nine sample interview questions.

Try saying an answer aloud. Notice where you pause, what needs an example and where your explanation could be clearer.

These are illustrative practice prompts, not a live AI session. They are not claimed to come from a particular employer.

Engineering interview questions

Technical reasoning1 / 3

An API works well in testing but slows down at peak traffic. Where do you start?

Think about the evidence you would gather before choosing a fix.

System design2 / 3

How would you design a notification service that can cope with a sudden spike in demand?

Talk through delivery guarantees, queues and what happens when a dependency fails.

Behavioural3 / 3

Tell me about a technical decision you changed your mind about.

Explain what you believed, what you learned and how your decision changed.

Product interview questions

Product judgement1 / 3

Customers ask for a feature, but usage data points to a different problem. How do you decide what to build?

Connect customer evidence, the underlying need and the outcome you would measure.

Prioritisation2 / 3

Two teams need your roadmap to move in different directions. How do you work through the trade-off?

Make the constraints visible and explain how you would reach a decision.

Behavioural3 / 3

Tell me about a product decision that did not work out as expected.

Describe your assumptions, the result and what you did next.

Leadership interview questions

People leadership1 / 3

A capable teammate is consistently missing commitments. How would you approach the conversation?

Consider the context, your expectations and the support you could offer.

Decision-making2 / 3

You need to make a decision with incomplete information. How do you move forward?

Explain what must be known now and which decisions can be revisited.

Behavioural3 / 3

Tell me about a time you helped a team work through disagreement.

Be specific about your contribution and what changed afterwards.

Your career story deserves care.

Our privacy approach

Different conversations.
The same useful habit.

Practise an answer, reflect on it and try again with a clearer point to make.

Behavioural

Make your contribution clear.

Start with a real situation. Explain your responsibility, what you did and what changed. Use the Story Bank to keep those examples together.

Explore Story Bank ↗
Technical

Explain the reasoning.

Clarify constraints, compare approaches and test your assumptions. Coding and system-design workspaces give that thinking a structure.

Role-specific

Connect the answer to the role.

Use the responsibilities in a job description to focus your practice. Bring relevant experience instead of memorising a script.
