I don't think I have ever been more than one week in to a job before I was given some form of admin level rights.
In small companies I can understand that. But I've had it also happen in government jobs, in big companies and startups that collect a lot of sensitive personal data.
In one case I was with a startup that had names, addresses, DOBs, phone numbers and debit/card details in their DB. When they hired me they didn't ask for references or ID. I was given full admin rights to their Azure account on day one.
If I were in charge I would at the very least want to validate a new employees ID before giving them any form of access to IT systems, and only elevate access privileges once they had an established track record within the company.
