Interview Process

The interview consisted of a technical phone screen focused on a CSV data verification problem. The candidate was required to parse the input and output in CSV format, implementing a structured approach using Object-Oriented Design (OOD). The problem had multiple parts, and the candidate was unaware of the total number of parts during the interview. They managed to complete four parts before time ran out.

Technical Questions

  1. Data Validation from CSV (data validation, string processing, OOD)
    • Part 1: Check if all fields for a given company are non-empty.
      • Output:
        • VERIFY: company name (all fields non-empty)
        • NON_VERIFY: company name (some fields empty)
    • Part 2: Validate the length of the full description to ensure it is between 5 and 31 characters.
      • Output:
        • VERIFY: company name (length requirement met)
        • NON_VERIFY: company name (length requirement not met)
    • Part 3: Check for any sensitive words from a given blocklist in the full description.
      • Output:
        • VERIFY: company name (no blocklist hits)
        • NON_VERIFY: company name (blocklist hit)

Tips & Insights

  • Focus on parsing the CSV correctly and keeping track of the requirements for each part.
  • Time management is crucial; be aware of how many parts there are and allocate time accordingly.
