All you have is a pre-loan investigation by the bank. Your colleague should not apply for a loan in a regular bank, but in a microfinance company. This kind of small loan company usually conducts pre-loan investigation through various telephone numbers reserved by the applicant, such as immediate family members, colleagues and friends. This has no effect on you.

You can remember that unless you are a guarantor, your colleagues will ask you to pay back the money after they can't afford it.

However, to become a guarantor, you must personally sign and sign a formal guarantee contract before it can take effect.

So, you don't have to worry about this situation at all. This is because your colleagues trusted you and wrote your number on the application form.

I hope my answer is helpful to you.
