Top 7 interview mistakes we see and how to avoid them

Top 7 interview mistakes we see and how to avoid them

Written by Nataliia Lugovska, Senior Talent Acquisition Specialist at Exness

After years of sitting on the other side of the interview table, one truth stands out: no candidate is ever perfect and that’s perfectly fine.

In today’s competitive job market, many applicants feel pressured to tick every box in a job description. But from a recruiter’s perspective, what truly makes a difference isn’t perfection. It’s preparation.

As a Senior Talent Acquisition Specialist, I’ve interviewed hundreds of candidates and reviewed feedback across every kind of role, from corporate positions to engineering. And while each conversation is unique, certain patterns appear time and again, small missteps that can blur an otherwise strong first impression or make great experience sound uncertain.

In this piece, I share some of the most common pitfalls I’ve seen and, more importantly, how to turn each one into an opportunity to stand out.

  1. Do your homework: Research the company you’re applying to before your interview. If you can’t answer basic questions about the business domain or product, it may raise doubts about your motivation. Even if a recruiter reached out to you, take the time to learn about the company, its industry, products, values, and reputation. This preparation will help you present yourself as professional, motivated, and well-prepared.

  2. Stay professional: Be yourself during the interview, but remember to follow professional etiquette. Avoid being overly casual, as an interview is not the same as a conversation with friends or peers. Since you don’t know your interviewer well enough for them to fully understand your personality or style, it’s best to maintain a formal tone.

  3. Know your story: Be ready to discuss your background and experience during every interview stage. Even if you’ve already spoken with representatives from the same company before, you may be meeting new people who haven’t heard your story yet.

  4. Answer with focus: Candidates often avoid answering direct questions, instead they give long responses that don’t address the information requested. Please try to keep your answers concise and focused on the question being asked. Also, prepare to give detailed responses to open-ended questions—short or vague answers (like yes/no or limited to one sentence) may prevent the interviewer from fully understanding the information they’re looking for.

  5. Own your impact: Many candidates tend to answer achievement-related questions with “We did” or “We worked on.” While it’s true that building a product or delivering a project is a team effort, it’s important to distinguish your own role and contribution. Highlight the technologies and tools you personally worked with, separate from those used by the broader team, and emphasize your individual achievements, impact, and contributions to the project’s success. Try framing your answers with “I did” or “I contributed.” This doesn’t come across as arrogant—in fact, it creates the right impression by clearly showing your value.

  6. Keep it positive: Avoid speaking negatively about former employers. It’s important to be honest about your reasons for leaving, but expressing criticism or using a negative tone may leave a poor impression on a potential manager. 

  7. Show genuine interest: Before each interview, prepare a list of questions you’d like to ask. Avoid staying silent during the Q&A session, and refrain from ending the interview by saying you have no questions. Doing so can give the impression that you’re not genuinely interested in the team, company, or project.

Ultimately, we can’t prepare for every single interview, but we can get ready for most of them. An interview isn’t just about proving you’re the perfect fit, it’s about showing genuine curiosity, professionalism, and self-awareness. 

Every conversation is an opportunity to learn, connect, and grow. Approach each interview with preparation and confidence, and you’ll not only avoid common mistakes but also leave a lasting, positive impression that sets you apart.
