Pretty easy first questions, centered around different networking protocols, ports and what their functions and shortcomings were. (What is telnet? Why is it considered unsecure? What does connectionless mean? TCP vs UDP?) Went into more hypothetical situations with how I would react and proceed. (How would you address a potential security incident?) Lastly, went into depth about my abilities and what I did at my role at the time. (What experience do you have with Splunk? What is the typical work day for you?)
