ByteDance Network Security Engineer interview questions

Applied online: After 3 days I passed the Interview Screening pass: HR Phone call to schedule a video interview. Round1: Technical Round (passed) Feedback duration was a week. An HR Phone call to schedule a video interview. Round2: Hiring Manager (He did not prepare well, he did not ask many questions to the candidate, He said sorry twice because of doing some other works). He asked me did you upload any same work files of your present company? I said, yes I did. then remained silent for 5-8 seconds. asked me to introduce myself twice. i was like silly.... I was very unsatisfied with his behavior.
