I gave an interview recently. I studied Spring Boot which is a vast topic but I covered the most. I studied all the java Trivia questions including Java 8 functional programming. Barely covered Hibernate. Studied REST APIs and high level design patterns. Covered collections/Multi Threading/ Strings/ Cloning/ Exceptions/ Deadlocks/ All Data structure etc etc.

I had one week to prepare for the interview. This is all I could cover including behavior and my projects. But what I got asked was totally different than what I usually do or covered. Like J2ee architecture style questions Applet, thin vs thick client, what kind of client a browser is etc. Which I couldn't answer.

My question is how is it posssible to know it all? I don't think a person who developed java would remember it all. I am so frustrated. I have worked on Backend side but I just don't remember text book style one liner trivia aswers like layers of J2ee Enterprise app. Sorry for ranting, can anyone tell me if you cover EVERYTHING for an interview or just leave it at luck that they hopefully ask from the topics you have covered?
