Git Interview Questions 2026, 35 Q&A on Branching, Merge vs Rebase, and Recovery
What changed in 2026 drives
Mass-recruiter offer letters are flatter for 2026 batch - the 4-5 LPA ASE band has barely budged in three years while inflation eats real wages. Premium tracks (Digital, Pro, Elite, Specialist) are still where the differential lives, and they are entirely test-driven. If you are aiming higher than the default offer, the coding round is not optional pageantry - it is the entire interview.
What I'd actually study for this
- 01Two solid coding-round answers (1 medium-hard DSA each, with edge-case discussion) > five half-baked ones
- 02One real project you can defend end-to-end - file paths, design decisions, and what you would change
- 03One DBMS schema you actually built (not a textbook ER diagram), with at least 3 join-heavy queries written from memory
- 04Three behavioural STAR stories: failure recovered, conflict handled, ownership taken
Where most candidates trip up
The single biggest mistake is treating company-specific guides as primary prep and DSA as secondary. It is the opposite. Mass recruiters use the test as a filter, but premium tracks at every IT services company use coding to allocate offer band. Spend 70% of prep time on DSA + system fundamentals, 20% on company-specific patterns, 10% on HR rehearsal. Reverse that ratio and you collect the default offer.
Editorial commentary by Aditya Sharma · written for PapersAdda · not generated, not aggregated.
Git fluency is assumed in 2026, and candidates report interviewers probe the parts people fake: rebase, reset vs revert, and recovery. Beyond add and commit, the questions test your mental model of commits, branches, and history. This guide compiles 35 questions from candidate-reported rounds and public preparation resources, each with commands and the trade-off being tested.
The mental model: a branch is just a movable pointer to a commit, and a commit is an immutable snapshot. Most Git confusion dissolves once this clicks.

|---|---|---|

| History | Rewrites it | Preserves it |
| Shared branches | Dangerous | Safe |
Use revert to undo on shared branches; reset for local cleanup. Candidate-reported as a top question.

a) deletes changes b) moves HEAD back and keeps changes staged c) pushes d) merges
Solution: Soft reset keeps the changes staged. Answer: (b)
Question 5
To find the commit that introduced a bug, use:

FAQ, Git Interview Questions
Q: How deep is rebase tested? Candidate-reported rounds expect the merge-vs-rebase trade-off and the golden rule: do not rebase shared history.
Q: Do freshers get Git questions? Yes, branching, staging, merge conflicts, and basic commands. Recovery and workflows skew mid to senior.
Q: Is the reflog commonly asked? Yes, as a recovery question. Knowing it signals real Git experience.
Q: What is the most-missed Git concept? reset vs revert and not rebasing shared branches, per candidate-reported feedback.
