<human>: I had a great (imo) phone interview yesterday for a technical support position and they want me in next week to see how I'll do on the software and on 'fitting in' I suppose. I was given a list of webinars to start with and to basically learn and be able to demonstrate how they work. I just totaled up the starting list and came up to six hours of videos to watch!

It was hinted that I should watch them multiple times and really be able to strut my stuff next week. Only I am a college student - I have an exam to study for, a shift at my current job to work over the weekend, three projects to put serious work in to and who knows what else - basically I'm worried about having the time to prepare fully.

Is this unusual? It seems like an entry level technical support position; sure I will need to know everything once I'm hired, but for right now I died a little inside upon doing the calculations (and that's only for one watch a piece). Any advice on what to focus on or do I just really need to commit myself to getting everything accomplished?

<bot>: second 'interview' next week, told to watch six hours of webinar videos multiple times and memorize them, is this uncommon, advice?
