Interview preparation for a Network Engineer focused on software (SDN + wireless)

Hi everyone! I did an internship last summer and right now I am applying for a full-time employment in that same company since i will graduate this semester (phd). I already had a couple of interviews but unfortunately the team I worked with during the summer won't have any position available for me.

Turns out, another team is interested in my application (yay!) but I am bit worried about the interview with them because the job description includes some wireless network responsibilities which I am not familiar with (in fact I didn't put any wireless technology on my resume).

I expect to get some questions about networking basics like ``what happens when I type example.com'', differences between TCP/UDP, DHCP, ARP, DNS, etc, but I am clueless about wireless related concepts and best-of-breed practices. Most of my experience is on the software side of things like writing SDN controller modules, REST APIs, microservices for network automation and management, and the like, but I rarely had to log into any network equipment (Switch, router, AP) and configure them, or do any kind of wireless/wired road map planning.

Do you have any tips, sources or areas where I should focus on before my interview (particularly on wireless)? I have about two weeks to prepare for it.

Thanks in advance! you are a great community!

PS: I am willing to provide more info if you need me to :)
