TransUnion Sr. Software Engineer interview questions

Interviewed with the technical recruiter. It was good. I sensed some hesitation around changes about mergers and acquisitions that recently happened with the company. Later week I was sent schedule technical interview. Even sent a reminder a day before. On the day of interview, I joined the team link sent to me and I waited and waited and waiter. Interviewer was a no show. I texted the recruiter, who has been pretty good about responding the other day, of course did not reply. Very unprofessional.
