CV is your first impression on the employer and it is through which employer judges whether you are suitable for the job or not. The most common mistake in a CV which results in rejection is making a general CV for all jobs.
Each job comes with specific requirements and your CV should highlight why you are fit for the required job and how your experience covers the field.
Too much information on your CV & Resume will mean it is not appealing to be read. If you feel that your CV is too long then read it again and remove lines which you think will not create an impact on the employer .
Many people add lies in the CV which may result in influencing the HR department and get you recruited but after getting job you will face problems. You will struggle to fulfill the expectations of the organization which can be embarrassing, demotivating and will also affect your growth.
