The entire process was pretty straightforward and tough because they want Support Engineers that know the fundamentals extremely well and can function well under duress. You need a very strong understanding of network fundamentals (OSI, TCP/IP, VLANs, etc...) and be able to apply those concepts to real life troubleshooting scenarios (this is obvious, but needs to emphasized). Although you don't need to regurgitate IOS commands, you will need to be able to verbally troubleshoot, so I recommend doing a lot of labs. Received a message on Linkedin, followed by a quick phone conversation. Phone Conversation w/recruiter: Very straightforward - the entire process was laid out thoroughly. A week later: 1) Phone interview w/manager consisting of a few personality questions (Experience, why networking...) and then some basic technical questions - the OSI model stack, encapsulation, how frames are transmitted. 2) Written Assignment A couple of days later: 3) Technical Video Conference interviews - I had 2 technical interviews over VC, each an hour long. These were pretty tough because the process is dynamic in the sense that the process is more interactive and the troubleshooting scenarios don't follow a specific prompt. Note: It's about how you think under pressure, not how many concepts/commands you can regurgitate. 4) In-person interview w/senior managers - a mix between personality and technical questions. The Support Engineers and their managers are really smart, so they can sniff out BS quickly.
