THE WORK BEFORE THE OPPORTUNITYAI-generated illustration“I used Redis to cache available seats.”
What happens when two students book the last seat?
A tool on your resume becomes a conversation about your decisions.
01Go one question deeper
A project description is a starting point. Explore the decisions, alternatives and failure cases behind it.
Example interview · not your assessment
What did you build?
The project
Where does a booking read and write seat availability?
The mechanism
Why cache availability instead of reading the database each time?
The decision
When would a database-only design be better?
The alternative
What happens when two students book the last seat?
The failure case
Example interview · not your assessment
The failure case
What happens when two students book the last seat?
The claim we're exploring“I used Redis to cache available seats.”

From preparation to possibility
Find a role worth preparing for. Put your work into words. Then practise the conversation.
03Evidence, then action
Feedback should show what you said, what still needs explaining, and a useful way to practise.
The answer, in your words
“I would check the available seats, then save the booking. Redis makes the read fast.”
Worked example · not your assessment
Describes a check before saving the booking.
Does not explain how the check and write stay safe when requests arrive together.
Recovery after a database outage was not asked in this example.
Your next 20 minutes
Sketch a safe booking flow for two simultaneous requests. Explain how it prevents overselling and name one trade-off.
A useful check: Show which operation protects the last seat, and what the second request receives.
04Connect your preparation
Use your preparation to make stronger claims—and practise the questions those claims invite.
A way to organise your practice. You choose when to move between tools.
05The difference is in the reasoning
Compare a vague implementation claim with an explanation that names a mechanism and its limits.
Worked example · written to illustrate reasoning, not a student result
The first explanation
“I used Redis to cache available seats.”
A tool is named. Its limits aren't.
With the reasoning made visible
“Redis speeds up browsing. Booking uses a conditional database update inside a transaction, so only an available seat can be claimed. A repeated request uses the same booking key. The cached seat count may lag; it cannot authorise a booking.”
The stronger explanation names the source of truth, handles competing requests, and states the cache's limit.
