7. Revealing too much personal information: Some of the jobseekers reveal their personal information like they are in very much need of money to run their family and discuss other personal problems to please them to give them the job. This is a big mistake because if they reveal their personal problems at once, the employer may think that you want to join their company only for money and other things and they lose all hopes of hiring you. So, try to avoid revealing your personal information and try to focus on what you bring to that position and organization.
