- Always clarify requirements and ask questions first
- Repeat the problem back to the interviewer
2. Not thinking out loud
- Interviewers want to see your thought process
- Explain your approach before writing code
3. Ignoring edge cases
- Always consider empty inputs, null values, and boundary conditions
- Test your solution with multiple examples
4. Writing code without a plan
- Discuss your approach and get agreement before coding
- Use pseudocode if needed
5. Poor time management
- Don't spend too long on one approach if it's not working
- Know when to ask for hints
6. Not testing your code
- Walk through your solution with test cases
- Fix bugs systematically
7. Getting nervous about silence
- It's okay to take a moment to think
- Better to pause than to ramble
8. Not knowing your resume
- Be ready to explain every project and technology listed
- Have specific examples ready
9. Skipping complexity analysis
- Always mention time and space complexity
- Discuss trade-offs between approaches
10. Not asking questions at the end
- Prepare 2-3 thoughtful questions about the team, tech stack, or culture
- Shows genuine interest in the role
Remember: Interview skills improve with practice. Do mock interviews regularly!

These are the most common pitfalls! The biggest mistake I see is not thinking out loud. Interviewers want to understand your problem-solving approach, not just the final answer. Another key point - always start with a brute force solution first, then optimize. It shows you can think systematically. Also never say you don't know something without attempting it first. Great list of mistakes to avoid!
