I received an unexpected call on Monday while grocery shopping, and the caller jumped straight into an interview without introducing themselves or mentioning the company. I had to ask for details about the role and the company, as I didn't recall applying for this position. After I did my usual pitch, the caller surprisingly invited me to meet the team the next day. He confirmed my email and promised to send more details, but I haven't received anything yet and the meeting is first thing in the morning. I don't even know the caller's name or position, and the number just connects to reception. I'm considering just showing up at 9:30 as planned and telling reception my name and the meeting details. Should I go for it?
