How would you find the element with a better run time? Remember the elements are not sorted and you can assume N is even. For example, input array [] = { 10, 2, 3, 10, 1, 4, 10...
Many people, Joel included suggest that a person who wants a job as a developer is asked to write code right in the interview. I think it is perfectly reasonable. If employed he will have to write lots of code and therefore the interviewer would want to check that interviewee really can write code and has not just listed all the words h...

A recruiter has sent me a fairly long quiz from an employer, and I think it's a bit excessive for what is supposedly a Senior Java developer role. The questions (to me) seem unfocused, and go into areas such as architecture, operations, capacity planning. One of the questions is this: "Internet-scale applications must be designed to pro...
All, I was promptly asked, upon showing up for phase 1 of an interview, to implement an http server in any scripting language I chose (Ruby/Python, etc.). I was not so accomplished in these languages, so I opted for Java. I was told I had 1 hour of time and I was told that the server must do the following: Reply with a 'hello' respons...

Recently, I have taken interviews and found that many of the questions are related to algorithms and math problems. I think that there are lots of things that are important other than algorithms, such as experience, domain specific knowledge, basic OS/compiler knowledge, etc.. Why do they ask so many algorithmic problems? ...

Having never thought about this, I replied back saying that the system will know the current context in which the flow of control is and decide the object to be used instead of this. The interviewer didn't look pleased ...
