Guys please help me, it's eating my mind

So I got a job as HR executive in a company with 40 employees but they don't have an EPF policy so I won't be having EPF account.

Now they'll provide me appointment letter, experience letter and salary slips and said it's enough to prove work ex but the problem is the salary slips is not computer generated it's made in excel -> printed -> signed and stamped. (Also the salary is not always on same date)

So my question is will it hinder my admission or placement? And it this enough to prove work ex?

PS: The company is registered under companies act and is also registered under GST.

(To anyone who want to know how 40 employees and still no EPF because the owner created 5 different companies stating it's a group and divided employees in it)
