1. Late to the interview.

Only an accident or act of God should make you late to a job interview. When possible, complete a full dry-run to the interview location a day or two before the actual interview. Always allow extra travel time, and plan to ideally arrive about 10-15 minutes early.

2. Inappropriate attire/grooming.

Arriving to the interview in unsuitable or ill-fitting clothing or with uncombed hair or body odour is completely unacceptable. Like it or not, appearance plays a major role in establishing a strong first impression.

3. Limited eye contact.

Job-seekers with limited interviewing experience may have difficulty maintaining strong eye contact throughout the interview, but doing so is key. If you feel weird looking into the interviewer’s eyes the whole time, try focusing on the bridge of his/her nose. In a panel interview, maintain eye contact with all the interviewers as you respond to questions.

4. Little evidence of research and knowledge about the company.

It is never acceptable not to have thoroughly researched the employer prior to the interview, and the silence you’ll hear when you can’t respond to a question about why you want to work there is your chance of receiving a job offer dying. Plus, how would you know you want to work for an organization if you haven’t completed any research?

5. Weak content: Incomplete and/or short interview question responses.

Probably the most common problem facing job-seekers in job interviews is responding with extremely short answers to interviewer questions. You can solve this problem by anticipating questions and developing compelling answers tailored to the job and employer

7. Appearing desperate for the job — or any job.

It’s an unfortunate truism of interviewing, but the job-seekers who appear the most needy for a job — regardless of the reality of the situation — are the least likely to receive the job offer. Even if you are desperate for a job, your goal must be to appear calm and confident to the interviewer(s).

8. Seeming unsure about job you want.

This deadly sin is most typical of younger and entry-level job-seekers who are often unsure of the type of job they seek. Again, conducting thorough research on careers and jobs can help clarify the jobs that best suit your skills, experience, and interests.

9. Badmouthing former bosses, co-workers, or employers.

Even if your former boss or organization is widely known for its incompetence’s or other problems, a job interview is no time to express your anger or disgust. Job-seekers who complain are immediately labelled just that — complainers — who should not be hired.

10. Failing to ask questions.

Most job interviews conclude with the interviewer asking the job-seeker is he or she has any questions. Failure to ask at least one non-obvious question here signals a level of disinterest (or laziness). In fact, if you have completed your research thoroughly, you should have more questions than you have time to ask.

Final Thoughts on Avoiding Mistakes, Achieving Interviewing Success-

Some other behaviours that did not quite make the top 10, but you should avoid if you want a better chance of acing the interview:

  • Bad habits and odd mannerisms (tapping fingers, cracking knuckles, fidgeting, touching face or hair, etc.)
  • Taking overly long pauses to respond to questions
  • Excessive use of “filler” words in your responses (ah, um, uh, like, you know)
  • Poor/too casual posture
  • Limp or moist handshake. (And no bone-crushers, either)
  • Gum chewing
  • Failing to turn cell phone to silent, or worse, answering your cell phone
  • Arguing with the interviewer
  • Not attempting to build rapport with interviewer
