It depends on the domain and the concepts the candidate is using in his/her current project. As we know every technology is vast, depending on the scenarios and domain each individual uses different technique. So I feel it is good if candidate knows in and out of some concepts what is being used.

I was rejected in couple of interviews where Interviewer went deep in frameworks or how this works internally in JVM or that works, which I found very wired, frameworks change quickly. In service industry it is demand vs supply and at the end a happy customer is required. I too take interview for my company and all I look in a candidate is how sharp the candidate is in his skills and how quickly he/she can solve a problem or get around it. I have seen people who are very good at answering above questions struggle a lot when actual work is required while a smart person learn things very quickly and gets the job done.<br /><br />The point I am trying to make here is if you are hiring a driver test his driving skills not his knowledge on how engine works or how the engine components are designed. I remember one of my colleague went for an interview with a company where he was asked to design his own hashmap and after selection all he is doing now is fixing bugs which he gets one or 2 in a week, and I was wondering how many candidates would have been rejected because of that question.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-694855878384792308.post-56227577639047770102014-12-26T04:11:35.809-08:002014-12-26T04:11:35.809-08:00Good Work Javin Paul

If a guy had experience in software development, class design, concurrency, data structures and algorithms, he is going to add value in team. Knowing some bits and pieces of Java questions is much easier than to develop skills needed for good software development and maintenance.

If someone can't explain why Java doesn't use operator overloading, maybe the candidate never used C++ and doesn't have a clue what it is. How many people use serialization? I have, but not often. We've got a couple sharp guys who have never used it, but if they had to, they'd have it figured out in no time. The important questions are about software structure, and class design. A person can write perfectly functioning software with a terrible design, and that is the danger. For example if you asked me "How do you create a thread-safe singleton in Java using double-checked locking?" I'd say, "I'm not going to create a singleton. Using global state is a bad design."Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-694855878384792308.post-89325587358517985652013-02-26T02:46:10.556-08:002013-02-26T02:46:10.556-08:00Nice Blog...Nice Blog...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-694855878384792308.post-87458878969364603112013-02-17T20:32:57.035-08:002013-02-17T20:32:57.035-08:00Most of the tough questions I faced on programming...Most of the tough questions I faced on programming interviews are from Data Structure and algorithm.
