This article speaks to me. I had experience on mainframe and wanted to get a job in Java. I learned Java however the interviewer would always say I was missing something. It could be J2ee, Jboss etc. with the Java ecosystem so large, can someone please help me how to learn. Is J2ee still in use or has all development moved to cloud. Where do I even begin to learn modern technologies. TIA.
I have only been asked once to answer specifics about the idiosyncrasies of a particular language or framework. Everything else I’ve been asked is about generic algorithms and data structures. Sorry that this doesn’t help much, I just find the kind of interview you encountered pretty frustrating.
Have all the companies you applied to been like that? Because clearly you and I have different interviewing experiences.
