Scenario:

You have a Git repository at /home/interview/repo with three recent commits on the main branch that were premature and need to be reorganized.

Task:

Undo the last three commits while keeping all changes in your working directory so you can recommit them properly.

Example:

# Before (three commits exist)
$ git log --oneline -4
d4e5f6a Third commit
c3d4e5f Second commit
b2c3d4e First commit
a1b2c3d Initial commit

# After (commits undone, changes kept)
$ git log --oneline -2
a1b2c3d Initial commit

$ git status
On branch main
Changes to be committed:
  modified:   file1.txt
  modified:   file2.txt
  modified:   file3.txt

Step 1: Navigate to the repository

cd /home/interview/repo

Navigate to the Git repository.

Step 2: Check current commit history

git log --oneline

See all commits including the three recent ones.

Step 3: Check current branch

git branch

Confirm you're on the main branch.

Step 4: View current status

git status

Should show clean working tree before reset.

Step 5: Reset last three commits (soft)

git reset --soft HEAD~3

Undo the last three commits while keeping changes staged.

Step 6: Verify commit history

git log --oneline

Should show three fewer commits.
