Personally, I think it is fake. Generally, large companies will leave their seat phone and fax numbers, and rarely leave their mobile phone numbers directly. Besides, it's a private cell phone. If you work for a company, do you use a landline or your own mobile phone to contact the business? Everyone is afraid of someone calling after work. In addition, the company address is not detailed. What street, building and floor is the human resources department in? Big companies are shy. Many people don't know what to do, so they walk around the building and usually write down the room number clearly. However, you can call to confirm. The most direct way is to check their human resources landline, call directly to ask if there is any recruitment plan, and introduce yourself by the way. It's hard to say. You're just looking for someone.
