Sleep, Stress, and Interview Days
Poor sleep raises stress before interviews — simple habits can help you show up sharper.

Why this matters
Interview days demand focus, recall, and calm under scrutiny. Stress and poor sleep interfere with all three. Many candidates lie awake rehearsing answers, then underperform because their brain is foggy, not because they lack ability. Small changes to the night before and morning of can improve how you come across — without needing a perfect routine.
Practical steps
Wind down the night before: dim screens, avoid late caffeine, and write tomorrow's plan so your mind is not spinning in bed. Prepare clothes, route, and documents early to reduce morning panic. Aim for a consistent bedtime in the days leading up, not just one heroic early night.
On the day, eat something sensible, hydrate, and build buffer time for travel delays. Use brief calming techniques you already trust — a short walk, slow breathing, listening to music. Reframe nerves as energy for performance. Arrive with time to compose yourself rather than rushing straight into the building. If sleep problems or stress are ongoing, speak to your GP or see NHS and Mind guidance — this article offers general wellbeing tips, not clinical treatment.
Common mistakes
Cramming preparation until midnight, then expecting peak performance. Over-caffeinating to compensate for tiredness, which can increase jitters. Skipping breakfast and crashing mid-interview. Arriving so early you sit anxiously for an hour. Treating one bad night's sleep as catastrophic — many people still perform adequately with reasonable coping strategies.
Avoid reviewing every possible question in the waiting area — it can spike anxiety. A short checklist of your key stories is usually enough. Trust the preparation you already did.
Watch note
Kelly McGonigal reframes stress as a response you can work with rather than only fight. That mindset helps on high-pressure days when your body is alert.
