Vertiv Software Engineer interview questions

I applied online. The interview took place in their new office. First, a young HR assistant (probably a student) took me into a small and awkward conference room with no window. On a phone call for an interview, they explicitly said there would be no tests, but I was immediately assigned two tests, an English language and a personality test. When I started writing, a HR representative came and started the conversation, after 15 minutes both the team leader and the manager came in. It was a mess. The interview was awkward and lasted about an hour and a half. HR is unprofessionally aggressive, about 45% of the questions concerned my current employer. No feedback was received after two weeks like they said, instead, feedback came in the fourth week after the interview.
