TL;DR

I would start with a protected main branch and short-lived feature branches. For normal work, changes go through PRs and CI before merge. For releases, the team can either deploy from main or cut a release branch if QA or stabilization needs to happen separately. For urgent production fixes, I would create a hotfix from the deployed version and merge the fix back into main.

Full answer below

Practice focus

Branching strategy, release safety, hotfix flow, CI validation, traceability, and team coordination.

Why this question matters
A branch strategy is not a diagram; it is an operating model for how the team delivers safely.
I would start with a protected main branch and short-lived feature branches. For normal work, changes go through PRs and CI before merge. For releases, the team can either deploy from main or cut a release branch if QA or stabilization needs to happen separately. For urgent production fixes, I would create a hotfix from the deployed version and merge the fix back into main.
Checkpoint
Stronger answer
Optional upgrade with examples, trade-offs, and sharper phrasing.
In a .NET product team, I would keep the strategy as simple as the release process allows. If the team deploys frequently, protected main plus tags and hotfix branches may be enough. If releases have long QA cycles, release branches can help isolate stabilization. The trade-off is that more branches mean more merge overhead and more ways for fixes to get lost.
Finish
Advanced answer
Optional deeper angle for production judgment and nuance.
I would design the strategy around deployment frequency, QA process, regulatory needs, and incident response. The key rules are: main stays healthy, production versions are traceable, hotfixes are validated, and fixes do not die on release branches. I would document the flow and automate checks so the process is not dependent on memory. A branching strategy that looks sophisticated but slows delivery or loses fixes is not useful.

Coding practice

Practice the problem like a real interview: restate, reason, implement, and test.

A hotfix flow might be: branch from the production tag, apply the fix, run CI and smoke tests, deploy, tag the hotfix version, then merge the hotfix back into main.

Review signals

Use these to catch weak phrasing, shallow reasoning, and risky claims.

Common mistakesCandidateCommon mistakesMistakes that weaken the answer or signal shallow understanding.Open details

Details

Creating too many long-lived branches.
Forgetting hotfix merge-back.
Deploying untagged commits.
Letting release branches drift from main.

Red flagsCandidateSigns the approach is fragileSignals that an interviewer may treat as risky.Open details

Details

Cannot explain why the strategy fits the team.
Uses GitFlow terminology without context.
Ignores CI and deployment traceability.
No plan for urgent fixes.
