• Speaking negatively about previous employers: Maintain a professional demeanor.
• Appearing unprepared: Research the company and the role before the interview.
• Failing to ask questions: Show your interest and engagement by asking thoughtful questions.

The Contrarian Truth: Technical Skills Aren’t Enough

Most candidates focus on listing technical skills. Interviewers actually want to see how you’ve used those skills to solve business problems and improve outcomes. Showing business impact is the key.

Scenario: Database Performance Crisis

Trigger: Users report slow application performance, impacting critical business functions.

Early warning signals: Increased CPU utilization, high disk I/O, long query response times.

First 60 minutes response: Identify the root cause using monitoring tools, prioritize critical queries, and implement temporary fixes.

What you communicate:

Use this email to update stakeholders.

Subject: Database Performance Update

“We’re experiencing performance issues impacting [Application]. I’ve identified the root cause and am implementing temporary fixes. I’ll provide another update in [Timeframe].”

What you measure: CPU utilization, disk I/O, query response times, number of users impacted.
