To give yourself the best shot at nailing the interview, follow these simple tips…

Morning of the Interview: Set Yourself Up for Success

1. Get Enough Sleep

A well-rested mind performs significantly better under pressure. Plan to get at least 7-9 hours of sleep the night before your interview. If possible, schedule your interview for the afternoon to avoid the stress of rushing in the morning.

2. Eat a Smart Breakfast

What you eat before your interview plays a critical role in your mental clarity, energy levels, and focus. Avoid sugary foods that cause energy crashes. Instead, go for a balanced breakfast:

• Protein (for sustained energy): Eggs, Greek yogurt, or nuts

• Fruits (for vitamins and brain function): Blueberries, bananas, or oranges

• Healthy fats (for cognitive function): Avocado or almond butter

Eggs, in particular, contain choline, a nutrient that enhances memory and focus—both crucial for recalling details and answering questions effectively.

3. Dress to Impress

Your attire should align with the company culture, but when in doubt, always dress one level above the expected dress code.

• A well-fitted suit or professional business attire demonstrates confidence and attention to detail.

• Ensure your outfit is clean, pressed, and free of distractions (wrinkles, stains, or excessive accessories).

• Comfort matters—you don’t want to be fidgeting with an uncomfortable outfit during the interview.

4. Get Your Blood Flowing

Light physical activity before your interview can boost your mood, calm your nerves, and improve mental clarity. You don’t need an intense workout—simple movements like stretching, a brisk walk, or yoga can do wonders.

Physical activity releases dopamine and serotonin, chemicals that help reduce anxiety and make you feel more optimistic and in control.

Before the Interview: First Impressions Matter

5. Arrive Early and Introduce Yourself

Plan to arrive 10-15 minutes early. Use that time to introduce yourself to the receptionist, security personnel, or anyone in the office. These small interactions help you get comfortable in the environment and leave a positive impression on company staff before the interview even starts.

6. Freshen Up and Boost Your Confidence

Before heading into the interview room, take a moment to check yourself in the restroom.

• Ensure your hair, outfit, and any accessories are in place.

• If you feel nervous, practice deep breathing exercises to calm your mind.

• Repeat positive affirmations like:

  • "I am confident and prepared."

  • "I have valuable skills to offer."

  • "This is an exciting opportunity."

A confident mindset can significantly impact how you carry yourself in the interview.

7. Turn Off Your Phone

This one’s crucial. Nothing ruins an interview faster than an unexpected phone ring or notification.

• Turn off your phone completely or switch it to airplane mode.

• If you rely on your phone for directions, put it away the moment you step into the building.

Distractions can make you appear unprepared, so eliminate them beforehand.

Final Thoughts: Set Yourself Apart

Interviews are about more than just answering questions correctly. They’re about making a connection, demonstrating confidence, and proving you're the best fit for the role.

By following these tips, you’ll walk into your interview feeling calm, prepared, and in control—ready to impress the hiring manager and land your next opportunity.
