Interview don’ts : Mistakes that cost you.

Take it from me, in the more than 12 years' experience I have conducting interviews and prepping candidates to successfully move forward in the process, here are some key don’ts.

The biggest don’t is “winging it”.

For all the candidates who told me “Don’t worry I always nail the interview” and did not take advantage of valuable insight, none moved to round 2 or got hired. Winging it never works. One of the biggest red flags in any interview is arriving unprepared. Failing to research the company or role suggests a lack of genuine interest and initiative, that’s never a winning formula.

“What Suzie says about Sally, says more about Suzie than it does Sally.” (Negativity speaks volumes.)

Speaking poorly of past employers, even if it happens unintentionally. Employers want to see professionalism and maturity, not negativity.

Nonverbal cues matter, so be aware of your physical presence.

Slouching, avoiding eye contact, or appearing distracted can overshadow even the strongest candidate. Be mindful of your attire as you have one chance to make a first impression, your overall appearance matters. Look polished, professional, show up confident and be genuine.

Vagueness never got anyone clarity or helped them get ahead. Be Clear when you communicate.

Answering questions vaguely, taking too long to get to the point and unstructured answers all can cost you. Make it easy for your interviewer, provide clear cut answers so they aren’t left lingering with more questions than answers. This may not be "your thing” but being aware of it is crucial, cutting off the interviewer shows a lack of self-awareness, while skipping thoughtful questions makes you seem disengaged.

At Thrive & Co, we know interviews are more than a Q&A they’re an opportunity to demonstrate curiosity, confidence, and alignment with the role and company. By avoiding these common “don’ts,” you’ll stand out as a prepared, professional, and self-aware candidate exactly the type employers want to hire.
