      If you apply sticky bit users can't the delete the files accidentally only owner can delete. SUID is useful when other user wanted to execute files with owner permissions. i hope you understand.

      I attended HPE interview recently. They have asked on virtualization, VMware etc. But that is not part of linux administration. And also many time have seen questions on RAID , LDAP , back up procedure etc for L3 which looks like advanced for a L1 candidate . Interviewer may ask sometimes questions related to his applications. Many times after L2 they will consider your profile for Devops. So if anyone looking for L3 and above, better to look into devops skills along which Linux. At least one or more scripting language is must.
