• Error Handling – Writing robust code that handles exceptions gracefully.

Example questions or scenarios:

• "Write a program to count the frequency of words in a text file."
• "How would you reverse a string without using built-in functions?"
• "Given a log file, extract all error messages and save them to a new file."

QA Methodology & Process

Beyond code, you need to understand the "why" and "how" of Quality Assurance. You will be evaluated on your ability to plan testing strategies and advocate for quality earlier in the development lifecycle.

Be ready to go over:

• Test Planning – Creating comprehensive test plans from vague requirements.
• Defect Lifecycle – How you track, prioritize, and verify bugs.
• Agile/Scrum – Your role in sprint planning and daily stand-ups.
• Types of Testing – Distinguishing between regression, smoke, sanity, and performance testing.

Example questions or scenarios:

• "How do you decide what to automate versus what to test manually?"
• "Describe a time you found a critical bug right before deployment. How did you handle it?"
• "How do you measure the effectiveness of your testing?"
