Find interview questions
for your next role.
Start with engineering questions on technical reasoning, system design and behavioural examples. Explore product and leadership prompts too. These free samples are available without an account.
Practise an engineering conversation.
Software engineering
Choose a focus, rehearse one answer and review it with a practical checklist.
System design
Work through a notification service, including capacity and failure behaviour.
Behavioural practice
Make your engineering contribution clear while keeping the facts intact.
STAR method examples
Structure any behavioural answer as situation, task, action and result, with three worked examples and common questions for every role.
Match the exercise
to your interview stage.
Confirm the format with your recruiter first. The guides below are preparation exercises, not employer question banks or predictions of what you will be asked.
Recruiter or introductory conversation
Practise a brief career introduction and explain why the responsibilities interest you. Choose one relevant example you can discuss honestly, then ask a follow-up that tests whether the role suits you.
Technical discussion
Choose engineering, system design or DevOps according to the expected task. State your assumptions before solving the problem, compare an alternative and explain how you would verify the result.
Behavioural or leadership discussion
Use the STAR guide to structure a decision, disagreement or setback. Separate your own actions from the team's and keep the outcome within what you can substantiate.
Read a guide, answer one question without looking at its explanation, then repeat the weakest part. These free exercises do not spend credits. For personalised text or voice practice, see the workflow and one-off pack pricing.
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.
Your original CV is temporary. MockReps keeps a minimised career profile for practice and is designed to delete the original after processing.
Different conversations.
The same useful habit.
Practise an answer, reflect on it and try again with a clearer point to make.
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 ↗︎Explain the reasoning.
Clarify constraints, compare approaches and test your assumptions. Coding and system-design workspaces give that thinking a structure.
Explore technical tools ↗︎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.
Build a relevant session ↗︎The next interview is
worth a few reps.
