Emergency mentor for quick JavaScript and Authentication ramp-up

I am interviewing for a job Monday which requires good knowledge of Authentication technology. Specifically, JWTs, OAuth, Authorization, SSO, all that stuff, as well as passing facility with JavaScript and/or Node.js. I have a long history in the tech industry, but these are specific technologies I have never learned very well, and I want to sound intelligent in the interviews Monday. The company gave me a technical exercise using their products, and I have struggled with it a bit because I'm shaky with all this stuff. I will need to demo my solution as part of this exercise, and this is what I specifically need help with. The solution is a Javascript web application which utilizes the company's widgets. I'm going to be studying my tail off this weekend, and what I'm looking for is someone who can be "on call" to help me prepare for this interview and demonstration. I would provide you with the exercise I am to complete, and all relevant information about the job, the company, and me. While I would be doing most of the work of course, I'm looking to have an expert in these technologies guide me and be available at a moment's notice all weekend (during regular daytime hours PST) to answer questions and work through issues, and help me gain deeper understanding while I ramp up. My vision is to use Slack and Team Viewer, and when I have a question I can quickly ping you and you'd be there within a minute or so. You could also help with my web application project, explaining what I'm doing wrong, how I can improve it, and how I can talk intelligently about it on Monday. So, this is for someone who already knows their stuff, and just has to answer questions from someone relatively new to JavaScript architecture and code, and also new to Authentication technologies. No idea how much work will be involved from you, all I really want is someone who's right there when I don't understand something. You'll be my immediate personal Google.
