Getting invited to a job interview is an important stage in your job search. It means your application has attracted the employer’s attention and you now have an opportunity to demonstrate your skills, experience and suitability for the position.

However, many candidates make avoidable job interview mistakes that can affect how they are perceived during the recruitment process.

An interview is not simply about answering questions correctly. It is also about demonstrating preparation, communication, professionalism, relevant experience and an understanding of the position.

Whether you are a fresh graduate attending your first interview or an experienced professional applying for a new opportunity, understanding common interview mistakes can help you prepare more effectively.

Here are 10 mistakes job seekers should avoid.

1. Arriving Late for the Interview

One of the most common job interview mistakes is arriving late without communicating with the employer.

If your interview is scheduled for 9:00 a.m., do not plan to arrive at 9:00 a.m. Instead, aim to be at the location early enough to deal with unexpected delays.

For interviews in Nairobi and other busy urban areas, consider:

• Traffic congestion
• Public transport delays
• Finding the building
• Security checks
• Parking
• Weather conditions
• Difficulty locating the office

If an unexpected problem will make you late, communicate with the interviewer as soon as reasonably possible.

For an online interview, log in early enough to check your microphone, camera and internet connection.

2. Failing to Research the Company

Another common mistake is attending an interview without knowing what the organisation does.

Before an interview, research the employer’s:

• Products or services
• Industry
• Target customers
• Website
• Recent activities
• Job description
• Company values where available

You do not need to memorise the entire company history.

You simply need enough knowledge to demonstrate that you understand where you are applying.

For example, if you are applying for a customer service position, you should understand what products or services the company provides and who its customers are.

This will also help you give more relevant answers during the interview.

3. Not Understanding the Job Description

A candidate can have good qualifications and still struggle during an interview if they have not properly read the job description.

Before attending an interview, identify:

• Main responsibilities
• Required qualifications
• Technical skills
• Experience requirements
• Soft skills
• Reporting responsibilities
• Performance expectations

Then think about examples from your experience that demonstrate your ability to perform those responsibilities.

For example, if the job requires customer complaint handling, prepare an example of a situation where you successfully dealt with a difficult customer.

4. Giving a Poor Answer to “Tell Us About Yourself”

“Tell us about yourself” is one of the questions many job seekers struggle with.

The interviewer is generally looking for a concise professional introduction, not your entire personal history.

A useful structure is:

Present: What do you currently do?

Past: What relevant experience do you have?

Future: Why are you interested in this opportunity?

For example:

“I am a customer service professional with three years of experience in customer relations and sales support. In my previous position, I handled customer enquiries, resolved complaints and supported the sales team. I am now looking for an opportunity where I can use these skills while taking on greater responsibility in customer relationship management.”

Keep your response relevant to the position.

5. Speaking Negatively About Previous Employers

You may have experienced challenges in a previous workplace, but an interview is rarely the right place to spend most of your time criticising former employers or colleagues.

If you are asked why you left a previous job, provide a professional and truthful explanation.

For example:

“I am looking for an opportunity that offers greater responsibility and allows me to develop my skills further.”

You can explain genuine circumstances without making the interview a discussion about workplace conflicts.

The focus should remain on your professional growth and what you can contribute to the new organisation.

6. Giving Generic Answers Without Examples

Saying:

“I am hardworking, honest and a team player.”

does not tell an interviewer very much.

Whenever possible, support your claims with examples.

Instead of saying:

“I am good at handling customers.”

say:

“In my previous role, I handled customer enquiries throughout the day. When a customer had a complaint, I first established the issue, explained the available solution and followed up until the matter was resolved.”

Examples demonstrate how you have actually applied your skills.

7. Not Preparing for Behavioural Questions

Many employers ask questions about situations you have experienced at work.

Examples include:

• Tell us about a difficult customer you handled.
• Describe a time you worked under pressure.
• Tell us about a disagreement with a colleague.
• Give an example of a problem you solved.
• Tell us about a time you failed and what you learned.

A useful method for answering these questions is the STAR method:

Situation: Explain the situation.

Task: Describe your responsibility.

Action: Explain what you did.

Result: Describe the outcome.

For example:

Situation: A customer was unhappy because an order had been delayed.
Task: I was responsible for handling the complaint.
Action: I checked the order status, communicated with the relevant department and explained the situation to the customer.
Result: The order was delivered and the customer received an update throughout the process.

This gives the interviewer evidence rather than general statements.

8. Failing to Ask Questions

At the end of an interview, the interviewer may ask:

“Do you have any questions for us?”

Responding immediately with “No” may mean you miss an opportunity to learn more about the position.

Consider asking:

• What would success look like in this role during the first three months?
• What are the main priorities for the person taking this position?
• How is performance measured?
• What does the team structure look like?
• What are the next steps in the recruitment process?

Choose questions that demonstrate genuine interest in the position.

9. Dressing or Presenting Yourself Inappropriately

Professional presentation is another area where candidates sometimes make avoidable mistakes.

The appropriate clothing can depend on the organisation, industry and role.

Regardless of the workplace, aim for a clean and professional appearance.

Pay attention to:

• Clothing
• Grooming
• Shoes
• Personal hygiene
• Overall presentation

You do not necessarily need expensive clothing. Neatness and appropriateness are more important.

10. Failing to Prepare for Online Interviews

Online interviews have become another important part of recruitment.

Candidates sometimes prepare their answers but forget to prepare the technology.

Before an online interview:

• Test your internet connection.
• Test your microphone.
• Test your camera.
• Charge your device.
• Check the meeting link.
• Find a quiet location.
• Make sure your background is appropriate.
• Keep your CV and job description nearby.

Do not wait until the interviewer calls before discovering that your microphone does not work.

How to Prepare for a Job Interview

Avoiding job interview mistakes starts with preparation.

Review Your CV

Read through your CV before the interview.

Be prepared to explain:

• Your previous responsibilities
• Your achievements
• Employment dates
• Qualifications
• Skills
• Career changes
• Gaps in employment where relevant

Never put information on your CV that you cannot explain.

Research the Employer

Visit the employer’s official website and social media platforms.

Understand what the organisation does and why the role exists.

Practise Common Questions

Practise answering questions such as:

• Tell us about yourself.
• Why do you want this job?
• Why should we hire you?
• What are your strengths?
• What is one area you are working to improve?
• Where do you see yourself professionally?
• Tell us about a difficult situation you handled.

Do not memorise answers word-for-word. Practise explaining your experience naturally.

Prepare Your Own Questions

An interview is also an opportunity to understand the role and organisation.

Prepare at least two relevant questions before attending.

What Should You Carry to an Interview?

Depending on the employer and position, you may need:

• Copies of your CV
• Academic certificates
• Professional certificates
• Identification documents where legitimately requested
• Portfolio or work samples
• Notebook and pen

Do not send sensitive personal or financial information simply because someone claims to be recruiting you. Verify the organisation and recruitment process first.

Kenya’s Employment Act provides the legal framework governing employment matters, including aspects of recruitment and employment relationships. You can read the current published legislation through Kenya Law – Employment Act.

How Fresh Graduates Can Prepare for Interviews

If you are a fresh graduate, you may worry that you do not have enough work experience.

Focus on what you can demonstrate.

Prepare examples from:

• Internships
• Industrial attachments
• Academic projects
• Volunteer work
• Leadership roles
• Group assignments
• Professional training

For example, if you led a university project, you can discuss how you organised the team, managed deadlines and handled disagreements.

These experiences can demonstrate transferable skills even when you have limited formal employment experience.

Continue Developing Your Skills

Interview preparation should not stop at practising questions.

If you identify a skill gap, look for legitimate training opportunities.

The National Industrial Training Authority provides information on industrial training, skills development and employment-related programmes through its official resources.

You can also explore Powervision Consultancy’s Training and Development services.

What Happens After an Interview?

The recruitment process may involve additional interviews, assessments, reference checks or other selection stages depending on the employer and position.

If you are not selected, avoid assuming that you are unsuitable for employment.

Use the experience to improve.

Ask yourself:

• Which questions did I struggle with?
• Did I give enough examples?
• Did I understand the job?
• Did I research the organisation?
• Was my communication clear?
• Was my CV consistent with my answers?

Each interview can provide useful experience for the next opportunity.
