which employers ask differentiating questions

(another blog post)

If an interview question is too tough, then strong or fake candidates both fail. If question is too common, then both pass. Good differentiating questions let the strong candidates shine through. Differentiating candidates depends on

* non-standard (but not obscure) questions, or
* drill-in on standard questions, or
* an interviewer capable of seeing the subtle differences among answers to standard questions.

If you have "none of the above", then you can't differentiate candidates.

Most interview questions are open-ended. I (not yet a strong candidate) can give super long answers to sleep-vs-wait, interface-vs-abstract-class, arrayList-vs-linkedList, "how to prevent deadlock".... However, many interview questions are so common that candidates can find perfect standard answers online. A strong interviewer must drill in on such a stock question to test the depth of understanding.

GS, google, lab49, MS, barc cap have good interviewers.
