ByteDance Senior Systems Administrator interview questions

The most insincere interview ever. Interviewed by a Senior System Administrator which was to me just passing through the motion of having to talk to another candidate. The session was less than 10 minutes and i can sense the person was trying to get out of the interview process ASAP. I was told the HR will be joining in the Zoom interview but after waiting for 45 minutes i realized this is not the company i will work for. They have no respect of people's time and made no effort to reply to my emails.
