Finding a job can be challenging, especially when facing constant rejection or silence from employers. Many jobseekers unknowingly make common mistakes that hold them back. The good news is that with small adjustments, you can significantly improve your job search success.

If you’re struggling to get interviews or job offers, here are five of the biggest job search mistakes unemployed candidates make—and how to fix them.

1. Applying to Too Many Jobs Without Tailoring Applications

Many jobseekers apply to dozens of jobs with the same CV and cover letter, hoping something will stick. Unfortunately, recruiters can spot generic applications instantly, and they often end up ignored.

The Fix: Quality Over Quantity

• Tailor your CV for each job by matching keywords from the job description.
• Write a customised cover letter that highlights your most relevant skills and experience.
• Use specific examples to demonstrate your achievements.

A few well-crafted applications are far more effective than sending out hundreds of generic ones.

2. Ignoring the Hidden Job Market

Not all job vacancies are advertised. Many roles are filled through networking, referrals, or internal hiring. If you’re only applying through job boards, you’re missing out on potential opportunities.

The Fix: Leverage Networking

• Update your LinkedIn profile to attract recruiters.
• Reach out to former colleagues, friends, and professional contacts.
• Attend industry events, job fairs, or webinars to meet hiring managers.

Networking can open doors to hidden job opportunities that you wouldn’t find through online applications alone.

3. Having an Outdated or Ineffective CV

A poorly formatted, outdated, or overly generic CV can instantly turn off recruiters. If your CV hasn’t been updated in years or doesn’t align with UK hiring expectations, you could be missing out on interviews.

The Fix: Optimise Your CV

• Keep it concise—no more than two pages.
• Use a clear, professional layout with headings and bullet points.
• Focus on achievements rather than listing job duties.
• Make sure it is ATS-friendly by using keywords from the job description.

4. Not Preparing Properly for Interviews

Many candidates assume they can “wing it” in interviews, leading to poor performance. Failing to research the company, prepare answers, or practise key skills can cost you the job.

The Fix: Prepare and Practise

• Research the company—know their mission, values, and recent news.
• Prepare strong answers for common interview questions, like:
  • “Tell me about yourself.”
  • “Why do you want to work here?”
  • “What are your strengths and weaknesses?”
• Use the STAR method (Situation, Task, Action, Result) to structure responses.
• Practise with a friend or in front of a mirror to build confidence.

The more you prepare, the more confident you’ll feel on the day.

5. Losing Motivation and Giving Up Too Soon

Job searching can be frustrating, and rejection can take a toll on your confidence. Many jobseekers lose momentum, stop applying, or settle for roles that don’t match their skills out of desperation.

The Fix: Stay Positive and Keep Moving Forward

• Set realistic goals (e.g., apply to 5 targeted jobs per week).
• Take breaks and look after your mental health.
• Use rejections as learning experiences—seek feedback and improve.
• Consider upskilling with free online courses to boost your employability.

Finding the right job takes time, but persistence and a proactive approach will lead to success.
