Top 5 Mistakes Candidates Make During Interviews (And How To Avoid Them)

Posted on

You’ve polished your CV, secured an interview, and are one step closer to landing your ideal role. But now comes the part that can make or break your chances — the interview.

At Imperium Financial Recruitment, we regularly support candidates through the interview process across accountancy, insolvency, and tax sectors. We’ve seen great candidates miss out simply because of small — but avoidable — mistakes. Here’s a breakdown of the top 5 errors we see time and again, and how to ensure you don’t fall into the same trap.


1. Lack of Preparation

The Mistake: Turning up without thoroughly researching the company, the role, or the people interviewing you.

Why It’s a Problem: Employers can quickly tell who has done their homework. Lack of research suggests you’re not genuinely interested in the role — or the company.

How to Avoid It:
Research the company’s services, recent news, values, and client base. Know the job description inside-out. If your interview is through a recruiter like Imperium FR, ask for an insight into company culture and interview style. The better prepared you are, the more confident and relevant your answers will be.


2. Talking Too Much (Or Too Little)

The Mistake: Giving long-winded answers that go off-topic, or giving short, vague answers that don’t say enough.

Why It’s a Problem: Poor communication makes it hard for interviewers to assess your suitability. Over-explaining can lose their interest; under-explaining fails to demonstrate your ability.

How to Avoid It:
Practice concise answers using the STAR technique (Situation, Task, Action, Result). Aim to answer questions clearly, then stop talking. Allow space for follow-up questions — it creates a natural flow and shows confidence.


3. Being Too Negative

The Mistake: Speaking poorly about previous employers, colleagues, or experiences.

Why It’s a Problem: Negativity can signal poor professionalism or suggest you may be difficult to work with.

How to Avoid It:
Even if your last role was challenging, focus on what you learned and how it’s helped your development. Keep your tone neutral and solutions-focused.


4. Not Asking Questions

The Mistake: Saying “I don’t have any questions” when asked at the end of the interview.

Why It’s a Problem: It makes you seem disengaged or uninterested in the company’s future — or your place in it.

How to Avoid It:
Prepare 2–3 thoughtful questions in advance. These might include:

  • “What does success look like in this role?”

  • “How is performance measured?”

  • “What’s the team dynamic like?”


5. Failing to Show Enthusiasm

The Mistake: Coming across as flat or indifferent — even if you’re interested.

Why It’s a Problem: Hiring managers want to bring in people who are genuinely motivated and excited to contribute.

How to Avoid It:
Smile, maintain eye contact (even on video), and express interest in the role and company. A little enthusiasm goes a long way in making you memorable.


Final Thoughts

Interviews are your opportunity to showcase not just your experience, but your personality, professionalism, and potential. By avoiding these common pitfalls, you put yourself in a much stronger position to succeed.
