Wednesday, June 11 — Switching Gears for Interview Prep

Pausing CKAD preparation temporarily to focus entirely on prepping for my Data Engineering interview. Cleared first round of interview which was yesterday. Gave cognitive+personality assessment tests today. Next I have two back-to-back 60 minute each technical interviews


🎯 Interview Focus Areas

The interview will focus on two key areas:

1. Programming & Technology

  • I need to sharpen my Python and SQL problem-solving.
  • Review coding patterns, edge case handling, and clean code practices.

2. System Design

  • Deepen understanding of:
    • System architecture for scalable data systems
    • Design patterns like event-driven, microservices, and batch/stream pipelines
    • Tradeoffs in storage, processing, availability, and latency

🛠 Plan of Action

  • Revise Python fundamentals and practice problems (LeetCode/Easy to Medium)
  • Brush up SQL joins, window functions, optimizations
  • Explore end-to-end data pipelines (batch + streaming)
  • Study system design specifically for data infra
