One of the most unprofessional and weird interviews I have ever experienced. I had a call with the recruiter and then another with the hiring manager. After this they invited me to their Bay Area office to give an in-person talk followed by multiple one-on-ones. This is when things got weird, they took a break for lunch and decided to take me to a *very* expensive restaurant. After which they told the interview had to be cut short because the person doing the last 1:1 wasn't in the office (?). Shortly after I got an email saying they were on a hiring freeze. I am not entirely sure but it sounded like they literally scheduled interviewees because they wanted to extract free lunch from the company.
