Perhaps you mean the company takes out personal questions in a job interview?

yes, I mean personal questions

Many personal questions are illegal in a job interview.

Prospective employers can't ask about a person's marital status, children, race, age, non-relevant health conditions, gender preference, or religion.

A company may want to take out personal effects (such as photos, documents, or personal belongings) during an interview for a couple of reasons:

1. Objectivity: By removing personal effects, the company aims to eliminate any bias or preconceived judgments based on personal information about the interviewee. This way, the focus remains solely on the candidate's qualifications, skills, and abilities relevant to the job.

2. Compliance: In some jurisdictions, there are laws or company policies in place to protect against discrimination during the hiring process. Removing personal effects helps ensure compliance with those regulations, as sensitive personal information, such as age, race, religion, or family status, is not visible during the interview.

To get more specific information regarding a company's reasons for removing personal effects, it would be best to inquire directly with the company's human resources department or the interviewers themselves.
