Collins Aerospace interview questions

Was contacted last minute for an interview which was earlier than the scheduled time. Interviewed by HR, said that the dept head was busy and will email for a Zoom interview, did not receive any email

Two stages of interview with other managers in first round (in person) followed by a video interview with the hiring manager who is based in the US. The first round interview was more intense as it was a panel interview with 3 other managers. The second round was done over a set of standard questions.
