I totally agree. I happily turn down a company that requires me to do C/C++ exams in the application process. I know my strength, which is coming up with new algorithms, or implementing them straight from a scientific paper, and most often efficiently enough to run on resource-limited robots. I know a lot of languages and technologies, which necessarily means my knowledge of those languages cannot all be in-depth. If I have to implement quicksort for a job interview I am applying for the wrong position. IMHO it's like asking a poet for the number of words (s)he can rhyme with "cat". :-)
