I need interview prep help... how can I get that on here?

Today I fumbled a technical interview.

I was told by the company I interned at previously to apply for a job posting. The person who knew the role is my manager from my internship there. That same manager I knew in there is now one position under the CTO. He told me it was a role that uses Spring Boot, Docker, and GraphQL. He said there’s a big effort to get GraphQL into the company’s architecture. It said “5+ years experience”, and didn't mention GraphQL, so I didn’t take it seriously. After I applied, the posting disappeared. My manager said the job posting I applied for was “probably just one of those ghost postings”. I had the behavioral where I spoke with the manager: I aced that. Today was the technical. The recruiter I was talking to was telling me this was an interview where I could show off projects, so I took the “prep some projects” approach. Did 3 projects. One using mern and GraphQL, one using typescript and express with rest architecture, and one using spring boot.  So I do that. I also prepped a Google doc with a list of common interview questions for all that I’m expecting. 

When I get into the interview, I get asked about my prior role. They said that showing projects wouldn’t be necessary: and that GraphQL wasn’t in the role. The first 20 minutes went well. I was asked about API stuff. I hear them say “good” sometimes, so I know something is right. Then I start getting asked simple questions I didn’t think to prep for. One was literally “what’s the difference between JDK and JRE”, and I knew what JDK was, but not JRE, and the difference between @override and @overload. I was then asked what Node is, so I tell them it’s a runtime environment (idk how I didn’t piece together what JRE was at this point), but I made a mistake because I should of delved into themes that made node.js incredible, like its event loop. Although I knew the basics of a microservice, it was only the basics. The interviewers were kind, and told me that although I articulated myself well, they’re looking for someone who knew more about microservices, and can code right now.

Luckily, the company told me prior to this that even if this doesn’t work out, they’d still want to hire me. There'll be another chance, but I realized I need mock interview help. I know I’ll need to review the Taro course on getting into and succeeding in interviews, but I also want to find people to do mock interviews with. How can I do that with Taro?

Thanks,
