interview will focus on network and security skills, plus windows and linux knowledge. You will meet with 1-2 senior engineers and manager. they will do background check. they also ask you which security product you have used, such as splunk SIEM

Very different from what I was used to. This is NOT a suit and tie place. That being said, they would much rather you feel comfortable in your own skin than look snazzy. They basically bring in various employees from the department to ask you questions related to things you might come in contact with on the job.
