Handling Difficult IT Interview Scenarios

When You Don’t Know the Answer

It’s okay not to know everything. Here’s how to handle it:

1. Stay calm and composed.
2. Be honest about not knowing.
3. Explain how you would find the answer or approach the problem.
4. Showcase your problem-solving process.

Example: “I’m not familiar with that specific technology, but I’m eager to learn. In similar situations, I’ve used [related technology] and I would approach learning this new one by…”

Dealing with Technical Questions Outside Your Expertise

1. Acknowledge the limits of your expertise.
2. Draw parallels to technologies you do know.
3. Express your willingness to learn.

Example: “While I haven’t worked directly with that framework, I have experience with [similar framework]. I’d be excited to apply my learning skills to quickly get up to speed on this technology.”

Common Mistakes to Avoid in IT Interviews

1. Overconfidence: Don’t claim expertise in areas where you’re not proficient.
