There are a few key mistakes you want to avoid before and during an interview:
- Failing to research the company beforehand.
- Speaking too little or too much
- Ignoring social cues from the interviewer (Are they ready to move on? Do they want to hear more?)
- Not being yourself
- Not taking the opportunity to ask questions
Having a strong skill set and years of experience do not automatically qualify you for a job, so make sure to actively work on improving your interview prowess through active analysis of your performance. You can avoid these stumbling blocks by first being aware of them, and then sidestep the issues altogether as long as you go in prepared.
