Super Micro Computer, Inc. (Supermicro) System Validation Engineer interview questions

The HR first contacted me and we arrange an first interview with a System Validation Engineer there. HR was nice and first interview comes quick which is next day. It's pretty simple, just ask your basical questions. Then the second interview is full of troubleshooting steps which im not too familiar with, I think that's why i get declined

overall experience was good, hiring manager reach out and carried onsite interview with team mates and resume based. it is decent company to start with and review time was 2 weeks
