Nearly everyone gets nervous before interviews. The problem is not the nervousness itself. It is what happens when anxiety starts affecting your performance: rushed answers, blank moments, fidgeting, and the frustrating sense that you are not showing the interviewer who you actually are.
Anxiety is a preparation problem (mostly)
Most interview anxiety comes from uncertainty. What will they ask? Will I be good enough? What if I freeze? The most effective anxiety reducer is also the most boring: preparation. When you have practiced your answers, researched the company, and reviewed the job description, you have eliminated the three biggest sources of interview uncertainty.
This does not mean over-preparing until you sound robotic. It means being familiar enough with your material that you can access it under pressure. Three focused practice sessions of 20 minutes each (spread across the days before your interview) do more for anxiety than a single three-hour cram session the night before.
The morning of: physical techniques
Cold water on your wrists. Run cold water over your inner wrists for 30 seconds. The pulse points there cool your blood quickly and activate a mild calming response. This works faster than deep breathing for some people and takes 30 seconds.
Walk for 10 minutes. A brief walk (around the block, through a parking lot, wherever you have space) burns off adrenaline and shifts your nervous system from fight-or-flight toward a calmer baseline. You do not need a 30-minute jog. Ten minutes of walking at a normal pace is enough to make a noticeable difference.
Eat something. Low blood sugar amplifies anxiety. Have a real breakfast or a snack that includes protein at least an hour before your interview. An empty stomach on top of nervousness makes both worse. Avoid excessive caffeine if you are already wired. One cup of coffee is fine. Three is not.
Controlled breathing. The 4-7-8 technique works: inhale through your nose for 4 seconds, hold for 7 seconds, exhale through your mouth for 8 seconds. Do this three times. The extended exhale activates the parasympathetic nervous system, which reduces heart rate and anxiety. According to breathing research from Harvard Medical School, controlled breathing is one of the most reliable acute stress reduction techniques available.
In the waiting room (or before the call starts)
Review your notes, not your worries. Spending the last five minutes before an interview scrolling through worst-case scenarios in your head is counterproductive. Instead, glance at your prepared talking points or your list of questions. Engaging your brain with concrete material interrupts the anxiety spiral.
Clench and release your fists. Tighten your fists as hard as you can for five seconds, then release completely. The muscle tension followed by release is a physical shortcut to relaxation that you can do invisibly in any setting.
Reframe the situation. You are not being tested. You are having a professional conversation to determine mutual fit. You are evaluating them as much as they are evaluating you. This reframe shifts the power dynamic in your mind from "I need to perform" to "I need to gather information and share my experience." It sounds simple because it is. It also works.
During the interview: when nerves spike
If you feel anxiety rising mid-interview, you have a few options that are invisible to the interviewer.
Press your feet firmly into the floor. This grounding technique creates a physical anchor that interrupts the mental spiral. Nobody can see your feet pressing down, but the sensation refocuses your attention on the present moment.
Slow your speech. When anxiety spikes, most people talk faster. Consciously slowing down your pace gives your brain time to catch up, reduces verbal fillers ("um," "like," "you know"), and projects confidence to the interviewer.
Take the pause. If your mind goes blank on a question, say "That is a great question, let me think about that for a moment." Then take five seconds. Five seconds feels like an eternity to you. It feels like a thoughtful pause to the interviewer. Interviewers generally prefer a brief pause followed by a clear answer over an immediate, rambling one.
The perspective that helps most
This interview is one conversation among many you will have in your career. If it goes well, great. If it does not, you will have another one. The stakes feel enormous in the moment, but very few single interviews are truly make-or-break for your career trajectory.
The interviewer is also a person who has been on your side of the table. They have been nervous in interviews. They have fumbled answers. They are not hoping you fail. Most interviewers are actively hoping each candidate is great, because finding the right hire makes their own job easier. You are walking into a room (or onto a call) with someone who wants you to be good. Let that lower the temperature a little.
