NXP Semiconductors Testing Engineer interview questions

Phone call with manager first, then 4 rounds of 1:1 interview. First 2 rounds purely behavior, next 2 rounds purely technical. Took really long to get back to me just to reject me. HM initially said I would hear back after 2-3 days but actually took more than 2 weeks to get back to me. Interviews overall wasn't hard except the 3rd round where he asked stuff I didn't learn in school yet.
