Don't slouch, vent or overshare: Do's and don'ts for job interviews

Job interviews can feel like an unpredictable game show. One wrong answer, and you’re out.

Nevertheless, with the right amount of preparation, you can still do well at the interview, regardless of whether you’re new to the workforce or a seasoned job hunter.

First, take a deep breath or a few, says Mirelee Keys, a Dubai-based corporate wellness coach. “It’s natural to feel nervous before an interview, but remember—this one moment doesn’t define you. Whether you land the job or not, it’s just one step in your journey. Keep reminding yourself: If this doesn’t work out, something else will. And most importantly, learn from any mistakes so you can ace the next one.”

So on that note, so here’s your guide to the do’s and don’ts of job interviews to help you leave a lasting and positive impression.

The do's

Do your homework

Walking into an interview without researching the company is like showing up for an exam you didn’t study for. Clarice Kent, a Dubai-based emotional intelligence coach and corporate wellness mentor, stresses the importance of being well-informed: “Check their website, read recent news, and understand their culture. When you walk in. knowing the company inside out, you immediately stand out. And above all, be crystal clear on the role you’re applying for, nothing kills an interview faster than confusion.”

Otherwise, expect awkward silences and puzzled looks—not exactly the impression you want to make.

Dress the part

First impressions matter. Whether it’s business formal or business casual, make sure you’re polished and professional. When in doubt, it’s always better to be slightly overdressed than underdressed. “It is advisable to at least look rather formal during the interview, even if you’ve heard that the office has a relaxed atmosphere. Dress smart, down to your shoes. Remember your shoes can really amplify your look, so don’t disregard them and turn up in slippers,” says Kent.

Arrive on time or even a little early

Abu Dhabi-based businessman Arun Kohli has a firm stance on punctuality. If you're late, you're out. “It’s an instant red flag. I’ve had candidates show up 10 to 15 minutes late, blaming traffic or even household errands. I get that life happens, but unless it’s a true emergency, plan better.”

His advice? Aim to arrive 10-15 minutes early. It gives you time to collect your thoughts, review your notes, and, most importantly, show respect for their time.

Bring the essentials

Both Kent and Kohli advise: Have multiple copies of your resume, a notepad, a pen, and any work samples you might need. A little preparation goes a long way. “It doesn’t speak too well, if you just show up for an interview empty-handed,” says Kohli.

 Be confident, not arrogant

Confidence is key, but cross into smugness, and you risk sinking your chances. Show enthusiasm, maintain good posture, and make eye contact—but don’t dominate the conversation or act like the company should be grateful to have you.

Cher Lillith, an Abu Dhabi-based media professional, recalls a candidate who confidently declared, “Oh, this place will be lucky to have me. Scratch that. Any place would be lucky to have me.”

She reflects, “I’m sure an organization will be fortunate to hire you, but let them figure that out. Show—don’t tell.”

Ask smart questions

At the end of the interview, you’ll likely be asked, "Do you have any questions for us?" Try not to say no. Instead, ask about company culture, growth opportunities, or what success looks like in the role.

The don’ts: Avoid these job-killing mistakes

Don’t insult your past employers

Even if your last boss was the worst, keep it professional. Speaking negatively about past jobs makes you look unprofessional and bitter. Kohli remembers, “There was one candidate who was just eager to take potshots at his previous employer. So I finally asked him, ‘Are you here for a job interview or to just vent?’”

Don’t overshare personal details

Yes, you want to be amiable, but oversharing about personal problems or unrelated topics can make things awkward. Keep the conversation relevant.  Kent laughs, “I’ve heard people relate their entire routines, down to their household troubles. Time is ticking, folks. We’ll hear the stories later,” she says.

Don’t lie

For example, don’t pretend that you know a language when you know four words, or studied it in school, 20 years ago. Kent recalls a candidate who insisted that they knew French and Spanish, but when tested, kept getting stuck at ‘Oui’, which means yes in French.

So, it might be tempting to exaggerate your skills or experience, but recruiters can see through fluff. Be honest—integrity goes a long way.

Don’t ramble

Answer questions thoroughly but concisely. Going off on long tangents can make you seem unprepared or unfocused.

Watch your body language

Slouching, avoiding eye contact, or crossing your arms can send the wrong signals. Sit straight and look alert, advises Kent.

Don’t forget to follow instructions

If they ask you to bring specific documents or complete a task beforehand, do it. Ignoring instructions makes you seem careless.

Interviews don’t have to be nerve-wracking if you’re well-prepared. Stay professional, show enthusiasm, and avoid common pitfalls. With these do’s and don’ts in mind, you’ll walk into that interview with confidence—and walk out with a job offer.
