I applied through college or university. The process took 2 months.

On Campus offer Amazon Interview Process — 2 Rounds

Each round combined two components:

• DSA (Data Structures & Algorithms) — a coding problem to solve live, evaluating problem-solving approach, coding correctness, and time/space complexity analysis.
• Amazon Work Style (Leadership Principles) — behavioral questions tied to Amazon's Leadership Principles (e.g., Ownership, Bias for Action, Customer Obsession), typically framed as "Tell me about a time when..." questions expecting STAR-format answers.

We are given:

• Logs from multiple computers
• Each log has format: Plain text [timestamp, log_message]

Goal: 👉 Merge all logs and print them in sorted order of timestamp

We’re given:

• source string
• encrypted string

We need to check if: 👉 The encryption mapping is valid

From the example:

• "abcda" → "zyxvz" → valid
• "acbb" → "yzxk" → invalid

So the rule seems: 👉 Each character in source should map to exactly one character 👉 Mapping must be consistent
